Github user bbende commented on the issue: https://github.com/apache/nifi/pull/1645 Sorry for taking so long to get back to this... I tested this using PutDistributedMapCache and FetchDistributedMapCache, and noticed the value coming back from fetch wasn't exactly what I had stored. In HBaseRowHandler we had: `lastResultBytes = resultCell.getValueArray()` And we need: `lastResultBytes = Arrays.copyOfRange(resultCell.getValueArray(), resultCell.getValueOffset(), resultCell.getValueLength() + resultCell.getValueOffset()); ` I made a commit here that includes the change: https://github.com/bbende/nifi/commit/dc8f14d95d6cdbab2aa6e815269fe0d98faa2fe6 I also moved MockHBaseClientService into it's own class so it can be used by both tests, so that we don't have to duplicate that code. Everything else looks good so I will go ahead and merge these changes together (your commit then mine). Thanks again for contributing! and sorry for the delay.
