Hi

 

Is it possible write a buffer into HDFS from UDF Impala (C++ or Java)? So I'd like simulate UDTF in Impala. First call to UDF to write output in HDFS. Later, another query reads these data from HDFS.

 

If it is possible, it will be with libhdfs. How can I install libhdfs-dev in debian wheezy?

 

 

Thanks!!!

Regards.
