bash - 如何从bash shell脚本运行beeline和hive查询

Question

登录到unix bash shell后，我可以按顺序手动运行以下步骤。

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/_HOST@BDS.XXXX.COM

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 "

我需要通过shell脚本test1.sh依次运行上述所有步骤

bash-4.2$ sh -x test1.sh

然后它将一直运行，直到beeline和其余命令未运行为止。
电流输出:

bash-4.2$ sh test1.sh

Answer 1

Bash正在逐行处理脚本。它运行beeline并等待您的输入。
您可以使用heredoc从脚本中写入标准输入:

beeline <<EOF
!connect jdbc:hive2://a301-1234-1234.stm.XXX.com:10000/default;;ssl=true;sslTrustStore=/app/bds/cloudera_truststore.jks;sslTrustPassword=;principal=hive/_HOST@BDS.XXXX.COM
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
