Bugs: RANGER-1856
    https://issues.apache.org/jira/browse/RANGER-1856


Repository: ranger


Description
-------

The directory for the kms pid is constant path in installer.

pidFolderName='/var/run/ranger_kms'
if [ ! -d "${pidFolderName}" ]; then
    mkdir -p "${pidFolderName}"
fi

The directory for the kms pid is configurable in ranger-kms and 
ranger-kms-initd.

if [ -z "${RANGER_KMS_PID_DIR_PATH}" ]
then
        RANGER_KMS_PID_DIR_PATH=/var/run/ranger_kms
fi
if [ ! -d "${RANGER_KMS_PID_DIR_PATH}" ]
then
        mkdir -p  $RANGER_KMS_PID_DIR_PATH
        chmod 660 $RANGER_KMS_PID_DIR_PATH
fi
pidf=${RANGER_KMS_PID_DIR_PATH}/${RANGER_KMS_PID_NAME}

The directory for the kms pid can be configured in install.properties.

#PID file path
RANGER_KMS_PID_DIR_PATH=/var/run/ranger_kms
