------------------------------------
Hi [~prasadm] [~gchanan], The failed hive test is
TestHDFSIntegration.testEnd2End. I explain the reason why the test is
failed(see the above). In my opinion, the location of loading policy file for
the LocalGroupMappingService is judged from the configuration. For example.
when the parameter fs.defaultFS is set hdfs://..., it should be load policy
file from HDFS. In the current source code of sentry, The
LocalGroupMappingService get the configuration just as following:
{code}configuration=new Configuration(){code}
May be it is doesn't matter for hive, because the core-site.xml and
hdfs-site.xml are on the classpath. But it is not the situation for Solr. Solr
has no chance to judge from configuration where the location is. The classpath
for Solr has not the core-site.xml,hdfs-site.xml. If
sentry.solr.provider.resource=/user/solr/sentry/sentry-provider.ini is set,
LocalGroupMappingService in the Solr doesn't judge where it is, hdfs or
localFilesystem. So it will default load the file from localFileSystem. Why the
the jira fired.
> Not able to read policy files on HDFS for Solr
