I was testing out the MR index build on a table with 1 billion rows. The map
reduce job completed but I got the following error at the end when it tries to
load the HFiles. Any idea what might be happening?
2015-07-31 23:39:39,746 ERROR [main] index.IndexTool - An exception occured
while performing the indexing job : java.io.IOException: Trying to load more

> Often, we need to create new indexes on master tables way after the data
> exists on the master tables. It would be good to have a simple MR job given
> by the phoenix code that users can call to have indexes in sync with the
> master table.
> Users can invoke the MR job using the following command
> hadoop jar org.apache.phoenix.mapreduce.Index -st MASTER_TABLE -tt
> INDEX_TABLE -columns a,b,c
> Is this ideal?
