Clean-up logs
-------------
Key: HIVE-2682
URL: https://issues.apache.org/jira/browse/HIVE-2682
Project: Hive
Issue Type: Wish
Components: Logging
Reporter: Rajat Goel
Priority: Trivial
Just wanted to cleanup some logs being printed at wrong loglevel -
1. org.apache.hadoop.hive.ql.exec.CommonJoinOperator prints "table 0 has 1000
rows for join key [...]" as WARNING. Is it really that?
2. org.apache.hadoop.hive.ql.exec.GroupByOperator prints "Hash Table completed
flushed" and "Begin Hash Table flush at close: size = 21" as WARNING. It
shouldn't be.
3. org.apache.hadoop.fs.FileSystem prints "Not initializing standby filesystem
because the needed configuration parameters fs.default.name{0|1} are missing."
as WARNING. Doesn't look like a problem since it is happening at very high rate.
4. org.apache.hadoop.hive.ql.stats.jdbc.JDBCStatsPublisher prints "Warning.
Invalid statistic." which looks fishy.
5. org.apache.hadoop.mapred.Merger prints "totalBytesProcessed: ABC is larger
than totalBytesExpected: XYZ" as ERROR at high rate...do we actually care about
this??
