[jira] [Commented] (TS-798) traffic_server crash if add non-existent plugin in remap rule

["Eric Balsa (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041786#comment-13041786 ] 

Eric Balsa commented on TS-798:
-------------------------------

My only comment is that we should exit on "remap parsing failure" and not continue startup (as it seems we do now). It would be confusing for users having a remap configuration where only a subset of remap directives were loaded properly due to some parsing error.
