Alan Gates commented on HIVE-9693:
----------------------------------
HiveConf.java
{code}
METASTORE_HBASE_CACHE_MAX_READER_WAIT("hive.metastore.hbase.cache.max.reader.wait",
"1000ms", new TimeValidator(TimeUnit.MILLISECONDS)
{code}
AggregateStatsCache
{code}
long maxReaderWaitTime =
HiveConf.getTimeVar(conf,
HiveConf.ConfVars.METASTORE_HBASE_CACHE_MAX_READER_WAIT,
TimeUnit.SECONDS);
...
isLocked = candidateList.readLock.tryLock(maxReaderWaitTime,
TimeUnit.MILLISECONDS);
{code}
It's wobbling between seconds and milliseconds. Write lock has the same issue.
Let's leave the pom change out as it will create a merge conflict since that
change has already been made in trunk.
Other than that +1.
