----------------------------------
Summary: ORC FileDump utility ignore 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
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.
