Prashant Pogde updated HDDS-633:
--------------------------------
Target Version/s: 1.2.0 (was: 1.1.0)
> HBase service fails to start with OzoneFS as defaultFS
> ------------------------------------------------------
>
> Key: HDDS-633
> URL: https://issues.apache.org/jira/browse/HDDS-633
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Filesystem
> Affects Versions: 0.3.0
> Reporter: Soumitra Sulav
> Priority: Major
>
> Hbase service fails to start when hbase.root-dir is pointing to OzoneFS.
> Below is the exception encountered :
> {code:java}
> 2018-10-10 20:12:52,255 ERROR [master/hcatest-4:17000] master.HMaster: Failed
> to become active master
> java.lang.IllegalStateException: The procedure WAL relies on the ability to
> hsync for proper operation during component failures, but the underlying
> filesystem does not support doing so. Please check the config value of
> 'hbase.procedure.store.wal.use.hsync' to set the desired level of robustness
> and ensure the config value of 'hbase.wal.dir' points to a FileSystem mount
> that can provide it.

> Above exception was also observed with YARN-atsv2 service as it uses embedded
> hbase and hence, WALs for storage. When I pointed the storage back to hdfs,
> exception was gone.
