             Summary: HiveHFileOutputFormat searching the wrong directory for HFiles?
                 Key: HIVE-13539
                 URL: https://issues.apache.org/jira/browse/HIVE-13539
             Project: Hive
          Issue Type: Bug
          Components: HBase Handler
    Affects Versions: 1.1.0
         Environment: Built into CDH 5.4.7

            Priority: Blocker


When creating HFiles for a bulkload in HBase I believe it is looking in the wrong directory to find the HFiles, resulting in the following exception:

{code}
Error: java.lang.RuntimeException: Hive Runtime Error while closing operators: java.io.IOException: Multiple family directories found in hdfs://c1n1.gbif.org:8020/user/hive/warehouse/tim.db/coords_hbase/_temporary/2/_temporary

The issue is that is looks for the HFiles in {{hdfs://c1n1.gbif.org:8020/user/hive/warehouse/tim.db/coords_hbase/_temporary/2/_temporary}} when I believe it should be looking in the task attempt subfolder, such as {{hdfs://c1n1.gbif.org:8020/user/hive/warehouse/tim.db/coords_hbase/_temporary/2/_temporary/attempt_1461004169450_0002_r_000000_1000}}.

This can be reproduced in any HBase load such as:

{code:sql}
CREATE TABLE coords_hbase(id INT, x DOUBLE, y DOUBLE)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES (
  'hbase.columns.mapping' = ':key,o:x,o:y',
  'hbase.table.default.storage.type' = 'binary');

SET hfile.family.path=/tmp/coords_hfiles/o; 
SET hive.hbase.generatehfiles=true;

INSERT OVERWRITE TABLE coords_hbase 
SELECT id, decimalLongitude, decimalLatitude
FROM source
CLUSTER BY id; 
{code}

Any advice greatly appreciated
