Summary: Improve the logic to detect writeId in catalogD
Key: IMPALA-14208
URL: https://issues.apache.org/jira/browse/IMPALA-14208
Project: IMPALA
Issue Type: Improvement
Reporter: Sai Hemanth Gantasala
Assignee: Sai Hemanth Gantasala
Comparing two ValidWriteIds logic in catalogD is currently little complicated.
It would be nice to simply this logic. This came out of review comment:
[https://gerrit.cloudera.org/c/21175/23/fe/src/main/java/org/apache/impala/catalog/HdfsTable.java#2988]
{code:java}
if (MetastoreShim.getMajorVersion() > 2 &&
AcidUtils.isTransactionalTable(msTable_.getParameters())) {
ValidWriteIdList writeIdList = fetchValidWriteIds(client);
prevWriteIdChanged = writeIdList.toString().equals(validWriteIds_);
validWriteIds_ = new MutableValidReaderWriteIdList(writeIdList);
} {code}
Typecasting writeIds to strings might be buggy. It would be nice to simplify
this logic.
