Zheng Hu commented on HBASE-21401: ---------------------------------- Seems it's related to SizeCachedNoTagsKeyValue.. > Sanity check in BaseDecoder#parseCell > ------------------------------------- > > Key: HBASE-21401 > URL: https://issues.apache.org/jira/browse/HBASE-21401 > Project: HBase > Issue Type: Sub-task > Components: regionserver > Reporter: Zheng Hu > Assignee: Zheng Hu > Priority: Critical > Fix For: 3.0.0, 2.2.0, 2.0.3, 2.1.2 > > Attachments: HBASE-21401.v1.patch, HBASE-21401.v2.patch > > > In KeyValueDecoder & ByteBuffKeyValueDecoder, we pass a byte buffer to > initialize the Cell without a sanity check (check each field's offset&len > exceed the byte buffer or not), so ArrayIndexOutOfBoundsException may happen > when read the cell's fields, such as HBASE-21379, it's hard to debug this > kind of bug. > An earlier check will help to find such kind of bugs. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
