HDFS HA not working

arunixas — Thu, 05 Feb 2015 23:28:51 GMT

Hi,

I am trying manually to set up hdfs ha with no luck.. I do everything exactly like here: http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cmug_topic_5_12_unique_1%29. but at the end, I'll get this error:

INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: Determined nameservice ID: mycluster
INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: HA Enabled: false
WARN org.apache.hadoop.hdfs.server.namenode.FSNamesystem: Configured NNs:

142 ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: FSNamesystem initialization failed.
java.io.IOException: Invalid configuration: a shared edits dir must not be specified if HA is not enabled.

Why ha enabled is false and system doesn't see my NNs (nn1,nn2).

Please advice me, what am i doing wrong...

Can you share your problematic core-site.xml and hdfs-site.xml contents here?

It is working! There was some misspelling or something in configuration, because next morning after good sleep, I tried once again and got running.
