> Key: HIVE-22771
> URL: https://issues.apache.org/jira/browse/HIVE-22771
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 1.2.1
> Reporter: Shivam
> Priority: Critical
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h

> Class _HCatOutputFormat_ in package _org.apache.hive.hcatalog.mapreduce_ uses function _setOutput_ to generate _idHash_ using below statement:
> +In file org/apache/hive/hcatalog/mapreduce/HCatOutputFormat.java+
> *line 116: idHash = String.valueOf(Math.random());*
> The output of idHash can be similar to values like this : 7.145347157239135E-4
>
> And,
> in class _FileOutputCommitterContainer_ in package _org.apache.hive.hcatalog.mapreduce;_
> Uses below statement to compute final partition path:
> +*In org/apache/hive/hcatalog/mapreduce/FileOutputCommitterContainer.java*+
> *line 366: String finalLocn = jobLocation.replaceAll(Path.SEPARATOR + SCRATCH_DIR_NAME + "{color:#FF0000}\\d\\.?\\d+"{color},"");*
> *line 367: partPath = new Path(finalLocn);*
>
> Regex used here is incorrect, since it will only remove integers after the *SCRATCH_DIR_NAME,* and hence will append 'E-4' (for the above example) in the final partition location.
