Hello. 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
