Thanks for your response Jarek :)I've started a new import run with --hive-drop-import-delims added and --direct removed (since the two are mutually exclusive), we'll see how it goes.Going to sleep now. I'll report back tomorrow :)--

we've seen similar behaviour in the past when the data itself contains Hive special characters like new line characters. Would you mind trying your import with --hive-drop-import-delims to see if it helps?
