Anoop Sam John commented on HBASE-14882: ---------------------------------------- I mean within HBase code base, where all put#addImmutable is being used? Some where in the WAL read code flow it is getting used for sure. That is what the failure u got when u have not made the new Cell to extend SettableSeqId > Provide a Put API that adds the provided family, qualifier, value without > copying > --------------------------------------------------------------------------------- > > Key: HBASE-14882 > URL: https://issues.apache.org/jira/browse/HBASE-14882 > Project: HBase > Issue Type: Improvement > Affects Versions: 1.2.0 > Reporter: Jerry He > Assignee: Xiang Li > Fix For: 2.0.0 > > Attachments: HBASE-14882.master.000.patch, > HBASE-14882.master.001.patch, HBASE-14882.master.002.patch > > > In the Put API, we have addImmutable() > {code} > /** > * See {@link #addColumn(byte[], byte[], byte[])}.
