Gabriel,
Thanks for the help, it's good to know that those params can be passed from the
command line and that the order is important.
I am trying to load the 100GB TPC-H data set and ultimately run the TPC-H
queries. All of the tables loaded relatively easily except LINEITEM (the
largest) required me to increase the
hbase.mapreduce.bulkload.max.hfiles.perRegion.perFamily to 48. After that the
file loaded.
This brings me to my next question though. What settings do I need to change
in order to count the [LINEITEM] table? At this point I have changed:
- hbase.rpc.timeout set to 20 min
- phoenix.query.timeoutMs set to 60 min
I am still getting an error, it appears to be an RPC timeout, as I have
mentioned I have already moved to an uncomfortably high setting. Is there some
other settings I should be moving and not necessarily the rpc.timeout?
For reference, here's the full sqlline interaction, including the error:
