HIVE 1.2.1 and Tez 0.5.2 or 0.7.0 works pretty well
beginning to use HIVE 2.0.0 and 0.8.x but not stable :/

ANALYZE TABLE COMPUTE STATISTICS => change stats for the table

ANALYZE TABLE COMPUTE STATISTICS for COLUMNS => change stats
for columns and should change it for columns but NOT for the table
That's it.

I have this error sometimes :
{noformat}
Error: Error while processing statement: FAILED: Execution Error, return
code 2 from org.apache.hadoop.hive.ql.exec.tez.TezTask. Vertex failed,
vertexName=Reducer 3, vertexId=vertex_1457964631631_0013_1_03,

1) If your metastore use a RDBMS for the backend, you can query it by
program.
2) If you want a more "command line" approach try the hcatalog cli tool
3) If you want to stay on hive, you could use beeline (HIVE as few meta
data commands like SHOW DATABASES)
Hope it helps,

There are no garantee.
Use a SORT BY and LIMIT BY if you want some sort of fixed result set.

For record,
We had the same issue in my company. We use Ambari and HDP. Ambari in HDP
2.5.3 doesn't provide well some configuration keys.
My advice for HDP users: checks the xml configuration files which Ambari
generate.

Another solution is to use HIVE over HBase.
When you insert in this table, HIVE do an upsert.

Could you please get hte result of this query:

see the udf
*parse_url_tuple*
SELECT b.*
FROM src LATERAL VIEW parse_url_tuple(fullurl, 'HOST', 'PATH', 'QUERY',
'QUERY:id') b as host, path, query, query_id LIMIT 1;

You could use CTAS in presto
