Hi, Docs says: "Shell interpreter uses Apache Commons Exec to execute external processes. In Zeppelin notebook, you can use %sh in the beginning of a paragraph to invoke system shell and run commands. Note : Currently each command runs as the user Zeppelin server is running as." Is there any way we can execute the shell interpreter as the current Zeppelin user? Like introducing a special shell for Apache Commons Exec, passing a $USER parameter etc? /Best regards, Mats

Hi @Shishir Jaiswal, Assuming HDP components on the Edge nodes such as clients and Knox then mixed versions are not supported. Knox for example only supports specific versions of an Hadoop service (see section 2.8.1.2 in http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_security/bk_security-20160829.pdf). Mixed OS versions do most times not affect things as long as it's fullfil all requirements around libraries, JVM versions etc. /Best regards, Mats

Hi @rama, You can delete the old container logs. If yarn.nodemanager.log-dir is full no new containers will start on that node. See also yarn.nodemanager.disk-health-checker.min-healthy-disks yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage yarn.nodemanager.disk-health-checker.min-free-space-per-disk-mb /Best regards, Mats

Hi @sivasaravanakumar k, The rate of replication work is throttled by HDFS to not interfere with cluster traffic when failures happen during regular cluster load. Some properties controlling this are dfs.namenode.replication.work.multiplier.per.iteration , dfs.namenode.replication.max-streams and dfs.namenode.replication.max-streams-hard-limit . The foremost controls the rate of work to be scheduled to a DN at every heartbeat that occurs, and the other two further limit the maximum parallel threaded network transfers done by a DataNode at a time. Some description of this is available at https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml /Best regards, Mats

Hi @Mahesh Mallikarjunappa, The Flume agent is typically listen to a logfile etc until it's aborted by an operator so that is where the"long-lived process" comes in. For more info on Flume please visit - https://flume.apache.org/FlumeUserGuide.html /Best regards, Mats

HI @Ron Buckley, Driver above are the ones which Hortonworks distribute and support. As AIX not is binary compatible with Linux any of the above drivers will not work with AIX. If you can get the source code you can compile it for AIX using the AIX Linux affinity libraries which according to IBM makes AIX Linux source code compatible. I also found Download ODBC connectors which is commercial AIX Hive ODBC driver from Progress Data Direct. /Best regards, Mats

Hi @Sunil Mukati, Yes it works with the "Generic" Database Type but it do not accept Netezza specific syntax. You also need to setup a DBCPConnectionPool and JDBC connection for your Netezza box. /Best regards, Mats
