cli.sh can not correctly identify Hadoop minor version numbers less than 20
---------------------------------------------------------------------------
Key: HIVE-902
URL: https://issues.apache.org/jira/browse/HIVE-902
Project: Hadoop Hive
Issue Type: Bug
Reporter: Carl Steinbach
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

% 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
