FileDump utility ignore errors when writing output)
> ORC FileDump utility ignores errors when writing output
> -------------------------------------------------------
>
> Key: HIVE-11073
> URL: https://issues.apache.org/jira/browse/HIVE-11073
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 1.2.0
> Reporter: Elliot West
> Assignee: Elliot West
> Priority: Minor
> Labels: cli, orc
>
> The Hive command line provides the {{--orcfiledump}} utility for dumping data
> contained within ORC files, specifically when using the {{-d}} option.
> Generally, it is useful to be able to pipe the data extracted into other
> commands and utilities to transform and control the data so that it is more
> manageable by the CLI user. A classic example is {{less}}.
> When such command pipelines are currently constructed, the underlying
> implementation in {{org.apache.hadoop.hive.ql.io.orc.FileDump#printJsonData}}
> is oblivious to errors occurring when writing to its output stream. Such
> errors are common place when a user issues {{Ctrl+C}} to kill the leaf
> process. In this event the leaf process terminates immediately but the Hive
> CLI process continues to execute until the full contents of the ORC file has
> been read.
> By making {{FileDump}} considerate of output stream errors the process will
> terminate as soon as the destination process exits (i.e. when the user kills
> {{less}}) and control will be returned to the user as expected.
