[jira] [Commented] (SQOOP-3188) Sqoop1 (import + --target-dir) with
empty directory (/usr/lib/hive) fails with error
(java.lang.NoClassDefFoundError: org/json/JSONObject)
[ https://issues.apache.org/jira/browse/SQOOP-3188?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16029229#comment-16029229 ]
Eric Lin commented on SQOOP-3188:
---------------------------------
Hi [~markuskemper@me.com],
I tried to test this against trunk code, it does NOT seem to be an issue for me. I created /usr/lib/hive directory with 777 permission and nothing under it, my sqoop import works as normal. Maybe it is environment specific?
