Gopal V updated HIVE-8328:
--------------------------
Description:
{code}
private void loadHashTable() throws HiveException {
if ((this.getExecContext() != null)
&& ((this.getExecContext().getLocalWork() == null) ||
(!this.getExecContext()
.getLocalWork().getInputFileChangeSensitive()))) {
if (hashTblInitedOnce) {
return;
} else {
hashTblInitedOnce = true;
}
}
{code}
This is not exiting in Tez, even if hashTblInitedOnce=true;
was:
TezCacheAccess needs to cache the pre-built MapJoinTableContainer object.
The issue is that it currently marks an object as being available in cache,
without keeping a strong in-memory reference to it.
> MapJoin implementation in Tez should not reload hashtables
