Subject: Hbase errors for  " ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing"


There's a quick work-around.

All regions get stuck when trying assigning themselves to host 'dtla1apps21' (from log message). It indicates the RS on that host how some becomes problematic.

In this case, you can stop the RS on that host which will trigger all STUCK regions to assign themselves to other RSs.

Actually, now I can see from the HBase page which regions are in the opening state. And the regions of these openinng states can now be queried£¬ but I don't know how to deal with this error of    " ERROR:org.apache.hadoop.hbase.PleaseHoldException: Master is initializing"

what version of hbase are you using?

If master is still initializing, then probably one of the regions in
transition is the region for meta, or a region for a system table (e.g.
hbase:namespace). You should check the master logs to
