Description:
Currently, NPE occurs during startup MySQLStore on initial state as following:
{code:xml}
Caused by: java.lang.NullPointerException
at org.apache.tajo.util.FileUtil.readTextFromStream(FileUtil.java:99)
at
org.apache.tajo.util.FileUtil.readTextFileFromResource(FileUtil.java:90)
at
org.apache.tajo.catalog.store.AbstractDBStore.readSchemaFile(AbstractDBStore.java:174)
at
org.apache.tajo.catalog.store.AbstractMySQLMariaDBStore.readSchemaFile(AbstractMySQLMariaDBStore.java:68)
at
org.apache.tajo.catalog.store.MySQLStore.readSchemaFile(MySQLStore.java:52)
