Namit Jain commented on HIVE-1903: ---------------------------------- +1 The changes look good > Can't join HBase tables if one's name is the beginning of the other > ------------------------------------------------------------------- > > Key: HIVE-1903 > URL: https://issues.apache.org/jira/browse/HIVE-1903 > Project: Hive > Issue Type: Bug > Reporter: Jean-Daniel Cryans > Assignee: John Sichi > Fix For: 0.7.0 > > Attachments: HIVE-1903.1.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
