--------------------------------
Summary: Non-interactive missing for the hbase-shell
Key: HBASE-27116
URL: https://issues.apache.org/jira/browse/HBASE-27116
Project: HBase
Issue Type: Bug
Components: shell
Affects Versions: 2.4.12
Reporter: Dong0829
During test 2.4.12, we found a lot of our integration testing failure for the
non-interactive mode in hbase-shell, looks like in 2.4.12, we removed the
"shell.eval_io" for the non-interactive shell, this caused the input/output
handle behavior for shell is the same which caused unexpected error, for
example:
```
echo -e "disable_all '.*'\ny" | hbase shell -n
=====Old version 2.4.4=====
t1
Disable the above 1 tables (y/n)?1 tables successfully disabled
Took 0.7811 seconds
=====New version 2.4.12=====
hbase:001:0> disable_all '.*'t1
test_tableDisable the above 2 tables (y/n)?
Took 0.5270 seconds
