Carl Steinbach updated HIVE-902:
--------------------------------
Attachment: HIVE-902.2.patch
- Adjusted regex to handle version numbers like "0.17.2.1"
- On error, now prints out string returned by 'hadoop version'.
- Verified that this works on Bash 3.2.17
> cli.sh can not correctly identify Hadoop minor version numbers less than 20

> cli.sh uses the following logic to detect the version of hadoop:
> version=$($HADOOP version | awk '{print $2;}');
> if [[ $version =~ "^0\.17" ]] || [[ $version =~ "^0\.18" ]] || [[ $version
> =~ "^0.19" ]]; then
> exec $HADOOP jar $AUX_JARS_CMD_LINE ${HIVE_LIB}/hive_cli.jar $CLASS
> $HIVE_OPTS "$@"
> else
> # hadoop 20 or newer - skip the aux_jars option. picked up from hiveconf
> exec $HADOOP jar ${HIVE_LIB}/hive_cli.jar $CLASS $HIVE_OPTS "$@"
> fi
> Apparently bash doesn't expect you to quote the regex:
> % ./bash -version
> GNU bash, version 4.0.0(1)-release (i386-apple-darwin9.8.0)
> % hadoop version
> Hadoop 0.19.0
> Subversion https://svn.apache.org/repos/asf/hadoop/core/branches/branch-0.19
> -r 713890

> % version=$(hadoop version | awk '{print $2;}')
> % echo $version
> 0.19.0 https://svn.apache.org/repos/asf/hadoop/core/branches/branch-0.19 by
> % [[ $version =~ "^0\.19" ]] && echo "Yes" || echo "No"
> No
> % [[ $version =~ "^0.19" ]] && echo "Yes" || echo "No"
> No
> % [[ $version =~ ^0.19 ]] && echo "Yes" || echo "No"
> Yes
