Ted,
You're right.
hbase-site.xml resolved problems 2 and 3, but...
Problem 4)
Spark don't push down predicates for HiveTableScan, which means that every
query is full scan.
== Physical Plan ==
TungstenAggregate(key=[],
functions=[(count(1),mode=Final,isDistinct=false)],
output=[count#144L])
+- TungstenExchange SinglePartition, None
+- TungstenAggregate(key=[],
functions=[(count(1),mode=Partial,isDistinct=false)],
output=[count#147L])
+- Project
+- Filter (added_date#141L >= 201601280000)
+- HiveTableScan [added_date#141L], MetastoreRelation
dwh_diagnostics, sessions_hbase, None
Is there any magic option to make this work ?
Regards,
Maciek
