> We have seen an issue whereby if the HDFS is unstable and the HBase master's HDFS client
is unable to stabilize before {{dfs.client.failover.max.attempts}} then the master's filesystem
object closes. This seems to result in an HBase master which will continue to run (process
and znode exists) but no meaningful work can be done (e.g. assigning meta).What we saw in
our HBase master logs was:{code}2016-12-01 19:19:08,192 ERROR org.apache.hadoop.hbase.master.handler.MetaServerShutdownHandler:
