[jira] [Created] (IMPALA-9867) Add Support for Spilling to HDFS

Yida Wu created IMPALA-9867:
-------------------------------

             Summary: Add Support for Spilling to HDFS
                 Key: IMPALA-9867
                 URL: https://issues.apache.org/jira/browse/IMPALA-9867
             Project: IMPALA
          Issue Type: Task
          Components: Backend
    Affects Versions: Impala 4.0
            Reporter: Yida Wu
            Assignee: Yida Wu


The task is to provide the basic capability of writing and reading from HDFS disk during "spilling to disk", as a sub task to fulfill "spilling to S3".

In theory, after the task is done, by changing the HDFS uri to S3 uri in HDFS connector should provide "spilling to S3" functionality.

Performance issues are to be considered in later tasks.
