Oozie shell动作随机抛出语法错误

Question

我有一个oozie shell动作，计划每天运行，执行一些hive命令，并将结果输出到stdoutput，以便被其他动作捕获。 但shell动作随机失败，有些日子会出现语法错误，其他日子也会成功。

任何帮助将不胜感激！

Shellscript.sh

    #!/bin/sh
ctr=0
loop=3
while [[ -z $personahistmaxdate  ||  -z $offeritemdimmaxdate  ||  -z $stgfirstgamedatemaxdate ]] && [[ ${ctr} -lt ${loop} ]];
do 
echo $ctr
personahistmaxdate=$(hive -e 'use identity; show partitions persona_hist;'|awk -F'|' '{print substr($1,length($1)-9, 10)}'|tail -1)
echo "personahistmaxdate=$personahistmaxdate"

offeritemdimmaxdate=$(hive -e 'use offer_item; show partitions offer_item_dim;'|awk -F'|' '{print substr($1,length($1)-9, 10)}'|tail -1)
echo "offeritemdimmaxdate=$offeritemdimmaxdate"

stgfirstgamedatemaxdate=$(hive -e 'use shooter_taxonomy_stg; show partitions stg_firstgamedate;'|awk -F'|' '{print substr($1,length($1)-9,10)}'|tail-1)
echo "stgfirstgamedatemaxdate=$stgfirstgamedatemaxdate"

 ctr=`expr $ctr + 1`
done

##Script to Handle if any of the variables is null then exit the shell

if [[ -z $personahistmaxdate  ||  -z $offeritemdimmaxdate  ||  -z $stgfirstgamedatemaxdate ]]
 then
echo "empty date in one of the variables"
exit 1
fi
