             Summary: HMaster start fails with IllegalStateException when HADOOP_HOME is set
                 Key: HDFS-13242
                 URL: https://issues.apache.org/jira/browse/HDFS-13242
             Project: Hadoop HDFS
          Issue Type: Bug
         Environment: HBase-2.0-beta1.

Hadoop trunk version.

java version "1.8.0_144"

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.
