I have changed the default hive 1.2 to hive 2.1 in hive-env.sh and then it worked properly.

Team, I am using HDP-2.6 and kerberos with hive1.2 and hive2.1 enabled. I have installed interactive hiveserver2 and it is running properly. I am facing the issue with beeline. I have spark2 installed and spark thrift server running.

@English Rose Yes I confirm that the settings which I mentioned is working properly.

rburagohain · ‎01-30-2017

@David Streever @Daniel Kozlowski Since my NN are in HA mode, so I have to provide the HA name in xasecure.audit.destination.hdfs.property as hdfs://cluster-nameservice:8020/ranger/audit. Also I added a new property xasecure.audit.destination.hdfs.batch.filespool.archive.dir=/var/log/hadoop/hdfs/audit/hdfs/spool/archive Now logs are coming in archive folder but the files are very big. [root@meybgdlpmst3] # ls -lh /var/log/hadoop/hdfs/audit/hdfs/spool/archive total 14G -rw-r--r-- 1 hdfs hadoop 6.0G Jan 29 03:44 spool_hdfs_20170128-0344.33.log -rw-r--r-- 1 hdfs hadoop 7.9G Jan 30 03:44 spool_hdfs_20170129-0344.37.log Now, is there any property for the log files so that they get compressed automatically as increasing the logs everyday in this stream will make the disk full at one day?? Thanks, Rahul

rburagohain · ‎01-29-2017

Hi Team and @Sagar Shimpi, The below steps helped me to resolve the issue. 1) As I am using HDP-2.4.2, so I need to download the jar from http://www.apache.org/dyn/closer.cgi/logging/log4j/extras/1.2.17/apache-log4j-extras-1.2.17-bin.tar.gz 2) Extract the tar file and copy apache-log4j-extras-1.2.17.jar to ALL the cluster nodes in /usr/hdp/<version>/hadoop-hdfs/lib location. Note: Also you can find apache-log4j-extras-1.2.17.jar in /usr/hdp/<version>/hive/lib folder. I found it later. 3) Then edit in advanced hdfs-log4j property from ambari and replace the default hdfs-audit log4j properties as hdfs.audit.logger=INFO,console log4j.logger.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.audit=${hdfs.audit.logger} log4j.additivity.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.audit=false log4j.appender.DRFAAUDIT=org.apache.log4j.rolling.RollingFileAppender log4j.appender.DRFAAUDIT.File=${hadoop.log.dir}/hdfs-audit.log log4j.appender.DRFAAUDIT.layout=org.apache.log4j.PatternLayout log4j.appender.DRFAAUDIT.layout.ConversionPattern=%d{ISO8601} %p %c: %m% log4j.appender.DRFAAUDIT.rollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy log4j.appender.DRFAAUDIT.rollingPolicy.maxIndex=30 log4j.appender.DRFAAUDIT.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy log4j.appender.DRFAAUDIT.triggeringPolicy.MaxFileSize=16106127360 ## The figure 16106127360 is in bytes which is equal to 15GB ## log4j.appender.DRFAAUDIT.rollingPolicy.ActiveFileName=${hadoop.log.dir}/hdfs-audit.log log4j.appender.DRFAAUDIT.rollingPolicy.FileNamePattern=${hadoop.log.dir}/hdfs-audit-%i.log.gz The output of the hdfs audit log files in .gz are: -rw-r--r-- 1 hdfs hadoop 384M Jan 28 23:51 hdfs-audit-2.log.gz -rw-r--r-- 1 hdfs hadoop 347M Jan 29 07:40 hdfs-audit-1.log.gz

Is there any additional configuration needs to be done?? Any help will be highly appreciated. Thanks, Rahul

@Sagar Shimpi I checked the above links but I didn't find how to compress and zip the log file automatically if it reaches the specified MaxFileSize. I need to compress the log files and keep it upto 30days which after then should get deleted automatically. So what are the additional properties should I need to add to make .gz files for hdfs-audit logs?? At present my property is set as: hdfs.audit.logger=INFO,console log4j.logger.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.audit=${hdfs.audit.logger} log4j.additivity.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.audit=false log4j.appender.DRFAAUDIT=org.apache.log4j.RollingFileAppender log4j.appender.DRFAAUDIT.File=${hadoop.log.dir}/hdfs-audit.log log4j.appender.DRFAAUDIT.layout=org.apache.log4j.PatternLayout log4j.appender.DRFAAUDIT.layout.ConversionPattern=%d{ISO8601} %p %c{2}: %m%n log4j.appender.DRFAAUDIT.DatePattern=.yyyy-MM-dd log4j.appender.DRFAAUDIT.MaxFileSize=1GB log4j.appender.DRFAAUDIT.MaxBackupIndex=30

Finally I am able to resolve the issue. 1. I changed the script extension from ambari_ldap_sync_all.sh to ambari_ldap_sync_all.exp 2. I also changed the absolute path of ambari-server as /usr/sbin/ambari-server and added exit statement at the end of script. #!/usr/bin/expect spawn /usr/sbin/ambari-server sync-ldap --existing expect "Enter Ambari Admin login:" send "admin\r" expect "Enter Ambari Admin password:" send "admin\r" expect eof exit 3. Finally inside the crontab, I made the entry as 0 23 * * * /usr/bin/expect /opt/ambari_ldap_sync_all.exp

rburagohain · ‎12-27-2016

@Jay SenSharma Yes expect package is already installed. Actually my issue is the script is not getting executed at 3pm even though it is configured in crontab. As I said, when I ran the command manually as ./ambari_ldap_sync_all.sh then it works. So is there any alternative how the script can get executed automatically from crontab?

rburagohain · ‎12-27-2016

Hi Team, I have used ambari-ldap sync script but I get the following error when I ran the below command.

Hi Team, I am using HDP 2.4.2 and I have 39 Datanodes in a cluster. Initially, there was 1GB heapsize of DN by default. Then it started to send warning alerts from every datanode even though there was no ingestion/job running. So, I increased the DN heapsize to 2GB but still it is sending me alerts consuming 60-70% heapsize and sometimes 80-90% even though cluster is idle. Is there any calculation/formula how much heapsize should I provide in Datanodes?? Please help. Thanks, Rahul

rburagohain · ‎10-12-2016

@Constantin Stanca Hi Constantin, The issue was that a hadoop folder got created previously under /usr/hdp folder since there should be only 2 folders named 2.4.2.0-258 and current under /usr/hdp. There should not be any additional folders apart from two folders. After removing the hadoop folder from /usr/hdp, the issue got resolved. Thanks, Rahul

@Deepak Sharma @Vipin Rathor Hi All, The users are in ou=staff,ou=lab,ou=users,dc=example,dc=com and groups are in ou=Groups,dc=example,dc=com and also users are syncing properly. In groups config, everything was correct. But the issue was in user search base which I had initially given as ou=lab,ou=users,dc=example,dc=com. So I changed the user search base to ou=staff,ou=lab,ou=users,dc=example,dc=com and then all my groups started to sync. Finally I can see my groups under groups tab in ranger. Thank you all for all the help and ideas you provided. Thanks, Rahul

Hi Team, During installation from ambari, the HDP clients successfully got installed in one of our datanodes. However it seems like there is some error in datanode which we are not able to troubleshoot the issue. The heartbeat response is receiving as can be seen in ambari-agent.log file.I am attaching the screenshot for your kind review. Can you please help us here?? Thanks, Rahul

@Harini Yadav Hi Harini, Thanks for the answer. However can you please help us in raising this concern as a bug for the above subject so that it will get available in the next release. Thanks, Rahul

rburagohain · ‎08-25-2016

ldaps-new.jpg Hi Team, I am trying to integrate Ranger with two HA Active Directory Servers. But how shall I configure two AD servers together from ambari in ranger while integrating with AD so that in case one AD server goes down, it will work from the secondary AD server automatically. Can you please let us know how it can be implemented?? I have two AD servers in HA mode, primary is 192.168.1.4 and secondary is 192.168.1.8. I am also attaching the screenshot where only one AD server is configured. Thanks, Rahul
