Hi Prajakta,
Thanks, I was able to generate a plan which was using indices by
following your advise.
However, I want to group on one key and count the others
"select count(id2) from table_t1 group by id1", would that not be possible ?
Also, could you give me an example of using indices to speed up
Hi Rohan
I run your queries on the same version from trunk and did not get any
errors. Not sure why you are getting a semantic analysis error. It would be
good if you could send me a snapshot of the error message.
About the second issue of getting the same plan even if you
set hive.optimize.index
Hi,
I running a query in Hive that generates 2 map reduce job. However, I noticed
that the settings are not propagated into the 2nd map reduce job. Is this a bug
or am I issuing the query incorrectly?
set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
set hive.exec.dynamic.par
