--------------------------------------

             Summary: Strings truncated to length 334 when hive data is accessed through hive ODBC driver.
                 Key: HIVE-3382
                 URL: https://issues.apache.org/jira/browse/HIVE-3382
             Project: Hive
          Issue Type: Bug
          Components: ODBC
    Affects Versions: 0.8.1
         Environment: Ubuntu Linux 10.04
            Reporter: abhijeet apsunde


I'm trying to fetch data from hive server using hive ODBC driver.

I observed that strings being fetched at application side are truncated to length 334, I further looked into the hiveclient code and found there are two variables which are hardcoded to “334”

./src/odbc/src/cpp/thriftserverconstants.h:static const int MAX_DISPLAY_SIZE = 334;
./src/odbc/src/cpp/thriftserverconstants.h:static const int MAX_BYTE_LENGTH  = 334;
 

I tried finding usage of these variables and looks like MAX_BYTE_LENGTH is causing issue of string truncation.
 

abhi@vmabhihive:~/hhh/ts/hive-0.8.1$ find . -type f -name "*.h" | xargs grep "MAX_BYTE_LENGTH"
./src/odbc/src/cpp/HiveRowSet.h:    /// Forces all data retrieved to be no more than MAX_BYTE_LENGTH
./src/odbc/src/cpp/HiveRowSet.h:    char m_field_buffer[MAX_BYTE_LENGTH + 1];


Expected behavior : Strings should be read completely [or upto length of application specified buffer length] instead of getting truncated to length 334.
