Subject [jira] [Commented] (HCATALOG-10) Shouldn't assume the secure hadoop installation
Date Sat, 17 Dec 2011 01:16:30 GMT

    [ https://issues.apache.org/jira/browse/HCATALOG-10?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13171397#comment-13171397

Julien Le Dem commented on HCATALOG-10:
---------------------------------------

You are correct, a class in the org.apache.hadoop.security.token package would be more appropriate.
In fact the isSecurityEnabled method itself is a good candidate.
{code}
try {
  UserGroupInformation.class.getMethod("isSecurityEnabled");
  Security.getInstance().handleSecurity(job, outputJobInfo, client, conf, harRequested);
} catch (NoSuchMethodException e) {
  LOG.info("Security is not supported by this version of hadoop.");
}
{code}
Then if it's present we are going to use it to check if security is enabled.
I'm attaching an updated patch: HCAT-10_a.patch

> HCatalog currently only builds against Hadoop 20S. It should successfully build against
hadoop-0.20 as well.
