-------------------------------------

             Summary: replay mutations to the wrong table?
                 Key: ACCUMULO-3603
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3603
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.6.1
            Reporter: Eric Newton
            Assignee: Eric Newton
            Priority: Critical
             Fix For: 1.6.3


A user writes to the mailing list:

Few times I noticed that some tables have values they cannot have, and
those entries have timestamp close to a tabletserver failure time.
(I mean wrong format, one table has msgpack values at least 10 bytes
long and another table has 1-byte values and after a failure I read
one or two 1-byte values in the table where I expect to read msgpack).

I suspect that during recovery process, when WAL is being read, some
entries are inserted to a wrong table.

May be it is a know bug as I am still using Accumulo 1.6.1

Consider adding multiple tables to the continuous ingest test to reproduce.

Note that the random walk test certainly does this, and no failures have been observed.
