To set the content-deposition header, the cn will look the file name in the system metadata first.

Fix issue in getDefaultReplicationPolicy.

Previously, under some circumstances, a ReplicationPolicy was created but was missing the optional replicationAllowed and numReplicas attributes. These are critical to the policy, so ensure they are set to sensible defaults even when property parsing errors and other issues might skip them. Added a test of this method, but I note that other methods in SystemMetadataFactory do not have unit tests and should be added if they are modified.

Use the "MNRead" to replace "MNStorage" to determine the version of the MN.

Change an exception to more appropriate exception.

Add more checks to avoid a null exception.

Add more debug statement for deleting.

Add some information about pid on the log statement.

Add a comment.

Removing xml_access table records now is in the removing the pid from hazelcast. So remove the dupicated code.

Check if the object and sysmeta are null before to get the inputstream object.
