Review comment:
yes, here we are catching as that, I was referring to line 144:if (line
== null) {
throw new
SemanticException(ErrorMsg.REPL_INVALID_CONFIG_FOR_SERVICE
.format("Could not read lastStoredTimeStamp from atlas
metadata file", "atlas"));
}
where we are throwing SemanticException already which we catch here, can't
we just throw the same e in that case?
