This issue is due a jline defect :
https://github.com/jline/jline2/issues/281, which is fixed in Jline 2.14.4,
bumping up JLine version in spark to version > Jline 2.14.4 will fix the issue
## How was this patch tested?
No new UT/automation test added, after upgrade to latest Jline version
2.14.6, manually tested spark shell features
