@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 ... View more

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 ...

Hi Team, The audit hdfs spool log files comes directly in /var/log/hadoop/hdfs/audit/hdfs/spool directory.

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

@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 ... View more

@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? ... View more
