Subject [jira] [Created] (HADOOP-12853) Change WASB documentation regarding page blob support
Date Mon, 29 Feb 2016 08:57:18 GMT
madhumita chakraborty created HADOOP-12853:

             Summary: Change WASB documentation regarding page blob support
                 Key: HADOOP-12853
                 URL: https://issues.apache.org/jira/browse/HADOOP-12853
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/azure
            Reporter: madhumita chakraborty
            Assignee: madhumita chakraborty
            Priority: Minor

WASB page blob support documentation in Features list at the top:

Supports both page blobs (suitable for most use cases, such as MapReduce) and block blobs
(suitable for continuous write use cases, such as an HBase write-ahead log).
Which is actually the opposite. Block blobs are better for typical big data use cases, and
page blobs were implemented to support the HBase WAL.

It is also mentioned that
"Page blobs can be used for other purposes beyond just HBase log files though."
This is not strong enough because page blob has been tested only in context of HBase write
ahead logs. They have not been broadly certified for use across the HDP stack, hence is not
recommended for use as a general purpose file-system via Hadoop cluster
