-------------------------------------
Summary: Corrupt KeyValue is silently ignored
Key: HBASE-22340
URL: https://issues.apache.org/jira/browse/HBASE-22340
Project: HBase
Issue Type: Bug
Components: wal
Affects Versions: 2.0.4, 2.1.2, 3.0.0, 2.2.0
Reporter: Peter Somogyi
Assignee: Peter Somogyi
When a KeyValue is constructed from a corrupt byte array then
IllegalArgumentException is thrown with a detailed message where the issue is
in the array. This is part of a sanity check introduced in HBASE-21401.
However, this is not logged at this time and the exception goes up to
ProtobufLogReader.readNext where it is caught, wrapped into EOFException and
the processing of the current WAL file is stopped.
There is only a TRACE level log message that could indicate if something went
wrong.
This will cause data loss without log message not just for the single corrupted
KV but for the rest of the WAL file.
