Add -e option
./hive -e --hiveconf MY_VAR =`cat /tmp/result/000000_0`;
But u could use the following hdfs command as well
MY_VAR=$(hdfs dfs -cat /tmp/result/000000_0)

Subject: Storing result of a query in a variable
I have a query whose result I wanted to store in a variable
How can I do it ?
./hive -e "use telecom;insert overwrite local directory '/tmp/result' select
avg( a from abc;"
./hive --hiveconf MY_VAR =`cat /tmp/result/000000_0`;
I am able to get average value in MY_VAR but it takes me in hive CLI which is not required
