I don't think that would work, where would you store the meta-data for the meta-data?

Hi  Ashish,
Thank you for your swift reply. I guess it's HiveServer code inherit the metastore thrift api. HiveServer provide metadata service by itself, not call another metastore server, and Hive.class talks to the HiveServer to get the metadata.

    Apologies for the delay Min..
The HiveServer code calls the metastore thrift api to get the
    metadata. The Hive.class in ql also talks to the metastore api to
    get the metadata. Not sure if I follow your question though?

        Hi guys,

        I found that HiveServer can fetch metadata thourgh Hive class
        after
        generated a task like DDLTask, and meanwhile Hive class is a
        client
        who ask HiveServer for metadata. So I guess it may be possible
        hiveserver both be a server and a client of itself, am I right?


        Thanks,
