"LOAD DATA INPATH" fails when the table already contains a file of the same name
--------------------------------------------------------------------------------
Key: HIVE-1996
URL: https://issues.apache.org/jira/browse/HIVE-1996
Project: Hive
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Kirk True
Assignee: Kirk True
Steps:
1. From the command line copy the kv2.txt data file into the current user's
HDFS directory:
$ hadoop fs -copyFromLocal /path/to/hive/sources/data/files/kv2.txt kv2.txt
2. In Hive, create the table:
create table tst_src1 (key_ int, value_ string);
3. Load the data into the table from HDFS:
load data inpath './kv2.txt' into table tst_src1;
4. Repeat step 1
5. Repeat step 3
Expected:
To have kv2.txt renamed in HDFS and then copied to the destination as per
HIVE-307.
Actual:
File is renamed, but Hive.copyFiles doesn't "see" the change in "srcs" as it
continues to use the same array elements (with the un-renamed, old file names).
It crashes with this error:
java.lang.NullPointerException
