When you run OfflineMetaRepair, most likely you will run it from your userid or root. Then we may get some opaque errors like "java.lang.AbstractMethodError: org.apache.hadoop.hbase.ipc.RpcScheduler.getWriteQueueLength()". If you check in HDFS, you may see that the meta directory is no longer owned by hbase: $ hdfs dfs -ls /hbase/data/hbase/ Found 2 items drwxr-xr-x - root hbase 0 2017-09-12 13:58 /hbase/data/hbase/meta drwxr-xr-x - hbase hbase 0 2016-06-15 15:02 /hbase/data/hbase/namespace Manually chown -R it and restart HBase fixed it for me.

Found my solution, i need to add 2 file: + db.hsqldb.properties + dn.hsqldb.script to the oozie job, then the job just work fine, still don't understand why because i don't need these 2 file when import.

Each file uses a minimum of one block entry (though that block will only be the size of the actual data). So if you are adding 2736 folders each with 200 files that's 2736 * 200 = 547,200 blocks. Do the folders represent some particular partitioning strategy? Can the files within a particular folder be combined into a single larger file? Depending on your source data format, you may be better off looking at something like Kite to handle the dataset management for you.

> GenericJDBCException: Could not open connection This implies Cloudera Manager is unable to connect to the database. If you're using the embedded postgresql database, ensure it is running. Visit the file /etc/cloudera-scm-server/db.properties. Use the authentication creds in it and try to connect to the database directly, like "psql -U user -p password database". Does it work?

This behavior is like any system with float representation, float bit representation does not allow exact representation of most values. There is a lot of literature on the subject like http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html If you want exact values it's better to go with decimal, where you can specify scale and precision. Thanks Szehon

Hi romain, I'm using CDH 5.2, i've add "[desktop] app_blacklist=" to the Service and Wide Configuration tab of Hue on Cloudera Manager but Spark still not show up on Hue. I also try to edit the hue.ini in /etc/hue/conf but nothing happen to, the desktop configuration tab on Hue still show this: app_blacklist spark Comma separated list of apps to not load at server startup. Default: Can you provide any help ? Thanks !

It looks like you asked for more resources than you configured YARN to offer, so check how much you can allocate in YARN and how much Spark asked for. I don't know about the ERROR; it may be a red herring. Please have a look at http://spark.apache.org/docs/latest/ for pretty good Spark docs.
