Subject [jira] Commented: (HADOOP-5307) Fix null value handling in StringUtils#arrayToString() and #getStrings()
Date Tue, 17 Mar 2009 05:40:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12682563#action_12682563

Chris Douglas commented on HADOOP-5307:
---------------------------------------

bq. Wish we had resolved HADOOP-5073, which will hopefully classify the "gray areas" in the
code.

Agreed. HADOOP-5073 is a necessary prerequisite for moving to 1.0, particularly for any remaining
Java-public APIs.

bq. I have opened HADOOP-5500, to fix the issue in DB context. I will close this one as won't
fix. If any other use case occurs for stringifying possible null object(s), we can reopen
this one.

Sounds fair.

> StringUtils#arrayToString() converts String array to a String of comma separated elements.
If the String array includes null values, these are recovered as "null" (literal) from getStrings()
method, which eventually causes configuration issues.
