Xiu commented on HIVE-10731:
----------------------------

We are calling hive in a proprietary setup, the query that passed on hive is:

{code:SQL}
CREATE TABLE Foo_Schema.TYPE  (
        TYPE int,
        ROW int
      )
      ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
      STORED AS INPUTFORMAT 'org.apache.hadoop.mapred.TextInputFormat' 
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
{code}

I can see the flow in ParserDriver.java, we call
{code:Java}
public ASTNode parse(String command) throws ParseException {
return parse(command, null);
}
{code}, the context is null. Which will result hiveConf to be not set in
{code:Java}
public ASTNode parse(String command, Context ctx, boolean 
setTokenRewriteStream) {}
{code} which propagate to HiveParser and throw a NullPointerException.
