> 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
