Crontab fail to start backup

[jongse park]

Hi,

I executed mysql cluster backup using crontab.
This is the error message:
-----------------------------------------------
[MgmtSrvr] ALERT -- Node 3: Backup request from 2 failed to start. Error: 1302
-----------------------------------------------

This is a backup script; backup.sh
-----------------------------------------------
#!/bin/sh

DATETIME=`date +%Y%m%d`
BASEDIR=/PRD_SQL/mysql_sql
BKDIR=/backup
BKCFG=${BKDIR}/config
BKLOG=${BKDIR}/log/mysql_full_cluster_${DATETIME}.log

find ${BKDIR}/log -name "*.log" -mtime +30 -exec rm {} \;


if [ -d ${BKDIR}/log ]
then
echo "Exist ${BKDIR}/log"
else
mkdir -p ${BKDIR}/log
fi

echo "MySQL Cluster backup end : `date +%H:%M:%S` " >> $BKLOG
---------------------------------------------------------------

The mysql cluster consist of 2 mgmd, 2 sqld, 2 ndbd.
1. When I execute the script. There is no error message.
./backup.sh
No error

2. ./bin/ndb_mgm -e "start bakcup 201505"
No error

3. When the backup is executed with crontab. There is the error message.
---------------------------------------------------------------------------
[MgmtSrvr] ALERT -- Node 3: Backup request from 2 failed to start. Error: 1302
---------------------------------------------------------------------------

Is there any bug for mysql cluster "Start Backup" with Crontab?


Please help me.

Thanks
