Hao Hao updated SENTRY-1643:
----------------------------
    Description: 
In MSentryPermChange/MSentryPathChange table, the changeID field is 
auto-increment. 
{noformat}<field name="changeID" primary-key="true" value-strategy="increment">
         <column name="CHANGE_ID" jdbc-type="BIGINT" allows-null="false"/>
       </field>{noformat}

However, found through the integration unit test TestHDFSIntegration, the value 
does not seem to be correctly auto increased. e.g Instead of increasing by one 
for each new entry, it increased by some unexpected number.
