how to run beeline and hive query from a bash shell script

I am able to run below steps manually in order after logging in to unix bash shell.

echo "Connecting beeline" 

beeline
!connect jdbc:hive2://a301-1234-1234.stm.XXX.com:10000/default;;ssl=true;sslTrustStore=/app/bds/cloudera_truststore.jks;sslTrustPassword=;principal=hive/[email protected]

INSERT OVERWRITE DIRECTORY "/dev/ref/HIVE_EXPORT/" ROW FORMAT DELIMITED FIELDS TERMINATED BY "," ESCAPED BY "\\" SELECT * FROM test_ref_st.Daily_report  limit 10;

hadoop fs -get('/dev/ref/HIVE_EXPORT/000000_0', '/user/rj/hiveExtract.csv')
echo "Query result extracted "

I need to run all above steps in sequence via a shell script test1.sh like

bash-4.2$ sh -x test1.sh

then it is only running till beeline and remaining commands are not being run. Current output:

bash-4.2$ sh test1.sh

Picked up JAVA_TOOL_OPTIONS:
Beeline version 1.1.0-cdh5.16.2 by Apache Hive

Solution

  • Bash is processing your script line by line. It runs beeline and waits for your input. You can use heredoc to write to stdin from your script:

    beeline <<EOF
!connect jdbc:hive2://a301-1234-1234.stm.XXX.com:10000/default;;ssl=true;sslTrustStore=/app/bds/cloudera_truststore.jks;sslTrustPassword=;principal=hive/[email protected]
INSERT OVERWRITE DIRECTORY "/dev/ref/HIVE_EXPORT/" ROW FORMAT DELIMITED FIELDS TERMINATED BY "," ESCAPED BY "\\" SELECT * FROM test_ref_st.Daily_report  limit 10;
EOF
