Grigore Lupescu updated HBASE-27742:
------------------------------------
Description:
The following bash shell script invocations may stall or not `hbase shell -n`
indefinitely. This might be how tty / pipes interact with the hbase shell.
Opening this to better understand either if this is a bug or limitation in
hbase shell, or what workarounds are there.
{color:#00875a}Works executed in CLI bash{color}
{code:java}
function check_alter_hbase () {
HBASE_SHELL_CMD="hbase shell -n"
hbase_state=$( echo "describe 'my_table'" | $HBASE_SHELL_CMD )
echo $hbase_state
}
export -f check_alter_hbase
timeout 30s bash -c check_alter_hbase{code}
{color:#de350b}Doesn't work as bash script, stalls until timeout ** {color}
{code:java}

Running the same bash stall logic in HBase 2.4.11 doesn't seem to reproduce the
issue, though there is a slight difference that we have containers there (e.g.
pod hbasemaster-0).
