32 machine cluster, HCatalog
Description
I made a table via Hive and tried some queries with Tajo.
But I can see resource allocation status in web interface is still very high even though the query finished successfully. Disk resource usage does not come back to 0 after query finished.
And because of this the next queries could not be executed without restarting Tajo.
Here's a brief summary of how i've met this issue
Tajo version : 0.8.0 and latest version on master branch, both HCatalog enabled while building Table : Table is partially materialized cube No Column name Type 1 time_hour TEXT 2 client TEXT 3 cache TEXT 4 httpcode TEXT 5 method TEXT 6 requestaddr TEXT 7 fqdn TEXT 8 server TEXT 9 direct TEXT 10 user TEXT 11 contenttype TEXT 12 referer TEXT 13 smartfilter TEXT 14 device TEXT 15 os TEXT 16 browser TEXT 17 sumts INT8 18 sumtt INT8 19 counts INT8 20 gid TEXT Table was made with Hive using GROUP BY and GROUPING SETS,and it is about 32GB Query : Executed a simple selection query (e.g. SELECT sumTS,sumTT,countS, client FROM htable WHERE client='58.186.210.28' AND gid ='2')
Unfortunately, I could not get any information from the log files, no exception has occured.
