Elliot West commented on HIVE-8396:
-----------------------------------
I expect we could introduce some full line comment filtering somewhere around
{{org.apache.hadoop.hive.cli.CliDriver.executeDriver(...):757}}:
{code}
...
while ((line = reader.readLine(curPrompt + "> ")) != null) {
if (!prefix.equals("")) {
prefix += '\n';
}
if (line.trim().endsWith(";") && !line.trim().endsWith("\\;")) {
line = prefix + line;
ret = cli.processLine(line, true);\
...
{code}
> Hive CliDriver command splitting can be broken when comments are present

> If the comment is moved after the command it works.
> I noticed this earlier when I comment out parts of some random q file for
> debugging purposes, and it starts failing. This is annoying.
