Hello Team

I am using Elasticsearch version 7.8.0.

I am using elasticsearch-sql-cli ; to perform my operations on elasticsearch index.

When I am using this and redirecting its output to a logfile , its output contains

WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.

                       SQL
                      7.8.0

My Command is :

echo "select userId from myindex;" | elasticsearch-sql-cli -s http://elastic:elastic@localhost:9200 | tee myindex_userids.log

Could you please help me , how to get rid of this. I want only index data in my output file.

Thanks

The tool will always print the header, currently. Feel free to open an issue asking for a parameter to execute one query on GH, though.
But you can of course pipe the output through smth like tail -n +30 to strip those first 30 lines (or whatever the right number).

But this Number say for example +30 , would change in future release ... as my Script would execute for given Elasticsearch Cluster which will be upgraded in future based on requirements and bug fixes.

This would be unstable solution for my implementations.

--silent option which is given is of no use , as it should have suppressed such things.

Also there is no option for redirecting the output to a file , so that what ever data is extracted would be captured in a log file.

Hello

As of now I am using below sed commands to erase the BANNER , sql> prompt from the output logfile.

sed -i '1,/sql>/d' ${LOG_DIR}/myindex_${DATE}.log          ## remove top lines till sql prompt
sed -i '1d; $d' ${LOG_DIR}/myindex_${DATE}.log             ## remove last line which has sql prompt

My work is done using these commands .. but I wonder this should not create any other issue in coming days ..

Thanks

Also I do not have github login ... hence as of now I cannot raise this in it.
