-----------------------------------
Summary: 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: Bug
Components: Ozone Filesystem
Affects Versions: 0.3.0
Reporter: Soumitra Sulav
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.
