Context
With Java client version below 8.0.2 version, running a batch write operation with sendkey= true results in "key mismatch - end of universe" error.Error in logs:
WARNING (rw): (rw_utils.c:316) key mismatch <digest> WARNING (rw): (rw_utils.c:260) key mismatch - end of universe?
Method
This bug has been fixed in java version (8.0.2) and other clients as well. Solution is to upgrade the java client to version 8.0.2 or above.The error might persists after upgrading the client, which could be due to the existing bad records. In order to fix this issue, delete those records (or truncate the entire set).
