-----------------------------------
You mean HBASE-21081 sir?
> Collectors.toMap uses a byte [] for key
> ---------------------------------------
>
> Key: HBASE-21080
> URL: https://issues.apache.org/jira/browse/HBASE-21080
> Project: HBase
> Issue Type: Bug
> Reporter: stack
> Priority: Major
>
> Good one found by a jxray spelunking [~mi...@cloudera.com].
> The below added by HBASE-19496 is making hashmaps with byte []s for keys
> (byte []'s don't do hashCode/Equals; usually when we have byte []'s for keys,
> we do ConcurrentMap and pass a Comparator in constructor that knows how to do
> byte []s).
> {code}
> .setStoreSequenceIds(regionLoadPB.getStoreCompleteSequenceIdList().stream()
> .collect(Collectors.toMap(
> (ClusterStatusProtos.StoreSequenceId s) ->
> s.getFamilyName().toByteArray(),
> ClusterStatusProtos.StoreSequenceId::getSequenceId)))
> {code}
