Hi all, I'm trying to fetch data from hive server using hive ODBC driver.
I observed that strings begin 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$<abhi@vm-abhihive:%7E/hhh/ts/hive-0.8.1$>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]; Does anyone know why 334 is hardcoded here and any specific reason for the number 334 ? Thanks, Abhijeet. -- Rgds, Abhijeet J. Apsunde
