John Sichi updated HIVE-1903:
-----------------------------
Status: Patch Available (was: Open)
This should fix it generically for all non-native tables (without disturbing
the prefix-matching logic for native tables). I'm still running through
regression tests though.

> I tried joining two tables, let's call them "table" and "table_a", but I'm
> seeing an array of errors such as this:
> {noformat}
> java.lang.IndexOutOfBoundsException: Index: 3, Size: 3
> at java.util.ArrayList.RangeCheck(ArrayList.java:547)
> at java.util.ArrayList.get(ArrayList.java:322)
> at
> org.apache.hadoop.hive.hbase.HiveHBaseTableInputFormat.getRecordReader(HiveHBaseTableInputFormat.java:118)
> at
> org.apache.hadoop.hive.ql.io.HiveInputFormat.getRecordReader(HiveInputFormat.java:231)
> {noformat}
> The reason is that HiveInputFormat.pushProjectionsAndFilters matches the
> aliases with startsWith so in my case the mappers for "table_a" were getting
> the columns from "table" as well as its own (and since it had less column, it
> was trying to get one too far in the array).
> I don't know if just changing it to "equals" fill fix it, my guess is it
> won't, since it may break RCFiles.
