Subject accumulo.root invalid table reference [SEC=UNOFFICIAL]
Date Mon, 20 Feb 2017 21:52:13 GMT
UNOFFICIAL

I have a situation where all tablet servers are progressively being declared dead.  From the
logs the tservers report errors like:

2017-02-....  DEBUG: Scan failed thrift error org.apache.thrift.trasport.TTransportException
null
(!0;1vm\\125.323.233.23::2016103<,server.com.org:9997,2342423df12341d)

1vm was a table id that was deleted several months ago so it appears there is some invalid
reference somewhere.

Scanning the metadata table "scan -b 1vm" returns no rows returned for 1vm.

A scan of the accumulo.root table returns approximately 15 rows that start with;

!0:1vm;<ip addr>::2016103 blah

How are the root table entries used and would it be safe to remove these entries since they
reference a deleted table?

Thanks in advance,
Matt
