[jira] [Commented] (HDFS-11046) Duplicate '-' in the daemon log
name
[ https://issues.apache.org/jira/browse/HDFS-11046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15601223#comment-15601223 ]
Akira Ajisaka commented on HDFS-11046:
--------------------------------------
First {{HADOOP_SUBCMD_SECURESERVICE}} is set to "false" by hadoop-functions.sh. When the variable is false, the else branch is not used in the following code.
{code:title=hdfs}
HADOOP_ROOT_LOGGER="${HADOOP_DAEMON_ROOT_LOGGER}"
if [[ -n "${HADOOP_SUBCMD_SECURESERVICE}" ]]; then
# shellcheck disable=SC2034
HADOOP_LOGFILE="hadoop-${HADOOP_SECURE_USER}-${HADOOP_IDENT_STRING}-${HADOOP_SUBCMD}-${HOSTNAME}.log"
else
# shellcheck disable=SC2034
HADOOP_LOGFILE="hadoop-${HADOOP_IDENT_STRING}-${HADOOP_SUBCMD}-${HOSTNAME}.log"
fi
{code}
I wrote a patch to use {{\[\[ "$\{HADOOP_SUBCMD_SECURESERVICE\}" = true \]\]}} instead.
