@Michael Bronson Hbase master does not come with apache-log4j-extras-1.2.17.jar jar file - hence it fails with error as "RollingFileAppender classnotfound error" As a workaround I copied the JAR file hiveserver2 to hbase master and restart the service then it starts working. cp /usr/hdp/current/hive-server2/lib/apache-log4j-extras-1.2.17.jar /usr/hdp/current/hbase-master/lib/ Please note that this is temporary workaround - If you will have to do this again in case of HDP upgrade.

@Sivasankar Chandrasekar may be you can create config groups in Ambari and then define it.

@Michael Bronson thats good - please mark the correct answer.

@Michael Bronson see my above comment - "FixedWindowRollingPolicy" (its not windows its window)is policy name - its nothing to do with OS

apappu · ‎08-15-2018

@Michael Bronson yes that is correct - please see attached my log4j configuration in ambari.log4j.txt

@Zack Atkinson not sure your answer is related to the question being asked - Am i missing some thing here? Please check my comment below for answer to the curl call issue.

Please use below config for size based rotation. log4j.appender.DRFA.layout=org.apache.log4j.PatternLayout log4j.appender.DRFA=org.apache.log4j.rolling.RollingFileAppender log4j.appender.DRFA.rollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy log4j.appender.DRFA.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy log4j.appender.DRFA.rollingPolicy.ActiveFileName =${hive.log.dir}/${hive.log.file}.log log4j.appender.DRFA.rollingPolicy.FileNamePattern=${hive.log.dir}/${hive.log.file}-.%i.log.gz log4j.appender.DRFA.triggeringPolicy.MaxFileSize=10000 log4j.appender.DRFA.rollingPolicy.maxIndex=10 I have tried this and it works perfectly fine. For some reason maxfilesize is not working if used like 1MB like that - so use live above. Note: please check hive-server2.err for any WARNINGS if does not work

@Zack Atkinson the curl call you are trying is incorrect. use cacert instead of cert curl -X POST --data 'Hello World! SSL Worked!''https:HOST:PORT/PATH '----cacert ./meyCert My example: curl -X GET https://c1111-node1.hdp.com:8443/#/login/local --cacert /tmp/knox.crt Please mark my comment as correct answer if this solves your issue.

Below properties can be used to configure the log4j settings for size based compressed backup. Here is an example for Hive service. log4j.appender.DRFA.layout=org.apache.log4j.PatternLayout log4j.appender.DRFA=org.apache.log4j.rolling.RollingFileAppender log4j.appender.DRFA.rollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy log4j.appender.DRFA.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy log4j.appender.DRFA.rollingPolicy.ActiveFileName =${hive.log.dir}/${hive.log.file}.log log4j.appender.DRFA.rollingPolicy.FileNamePattern=${hive.log.dir}/${hive.log.file}-.%i.log.gz log4j.appender.DRFA.triggeringPolicy.MaxFileSize=10000 log4j.appender.DRFA.rollingPolicy.maxIndex=10 For some reason maxfilesize is not working if used like 1MB like that - so use live above. Note: please check console log (.out or .err) for any WARNINGS if does not work

@Zack Atkinson Using curl to make REST API call to https you have 2 options. 1. Do insecure connection/call with "-k" option - this option tells to curl that simply trust the server cert and do the post. Ex: curl -k -X POST --data 'Hello World! SSL Worked!''https:HOST:PORT/PATH' 2. You don't need to provide private key - just public cert is good enough. Ex: curl -X POST --data 'Hello World! SSL Worked!''https:HOST:PORT/PATH'--cert ./meyCert
