Hi All,   We recently added 11 new datanodes to CDH5.3.2 cluster which has 20 datanodes. I see HDFS Balancer slowly moving blocks say avg 4000 blocks peer 10 mins. I' updated Balancer Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml with    <property> <name>dfs.balance.bandwidthPerSec</name> <value>3048576000</value> </property>   still i see alomst same speed, i checked network graphs also   Is there any other setting required?   Thanks, Venu ...

Hello All,   I'm facing a access problem with hive user when quering external table in CDH 5.3.2 after sentry enabled I created a external table on top of a mapreduce output directory in hdfs. After mapreduce when i query external table it say's    Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=hive, access=READ_EXECUTE, inode="/data/payload_preprocessor/maptemp":svcvmhdpdev:hadoop:drwxrwx---   where svcvmhdpdev is the user who launched mapreduce job and  /data/payload_preprocessor/maptemp is mapreduce output direcotry (also i crearted external table using this location)   I used follwing query to grant ALL pervillges to hive user  but it's not working   GRANT ALL ON URI 'hdfs://data/payload_preprocessor/maptemp' TO ROLE admin_role;   Only option is set HDFS ACL's, but /data/payload_preprocessor/maptemp is a mapreduce output directory which need to be deleted everytime before mapreduce job.   Question is how do i grant read permissions to hive user permanently even directory deleted and created again?     Thanks, Venu ...
