Kirk True commented on HIVE-1996:
---------------------------------
This is very closely related to, but not the same as, HIVE-307. That bug
specifically pertains to {{LOCAL}} files.
> "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:
> {noformat}
> java.lang.NullPointerException
