> HIVE-2372 was originally created in response to this error message, however
> that patch was merely a work-around to handle the condition where
> mapred.input.dir is too long.
> Any other environment variable that is "too long" for the host OS will still
> cause a job failure.
> In my case:
> While creating a table with a large number of columns, a large hive variable
> is temporarily created using SET, the variable contains the columns and
> column descriptions.
> A CREATE TABLE statement then successfully uses that large variable.
> After successfully creating the table the hive script attempts to load data
> into the table using a TRANSFORM script, triggering the error:
> java.io.IOException: error=7, Argument list too long
> Since the variable is no longer used after the table is created, the hive
> script was updated to SET the large variable to empty.
> After setting the variable empty the second statement in the hive script ran
> fine.
> Hive should more gracefully notify the user as to the cause of the problem
> and offer a configurable approach for automatically handling the condition.
> In this case, originally identifying the cause of the issue was somewhat
> confusing since the portion of the hive script that referenced the long
> variable ran successfully, and the portion of the script that failed didn't
> even use/reference the variable that was causing that portion to fail.
> Since HIVE-2372 has already been "Fixed" this JIRA re-opens the issue since
> the original issue was worked around, not resolved...
