>                 Key: HDFS-8012
>                 URL: https://issues.apache.org/jira/browse/HDFS-8012
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: datanode, hdfs-client
>            Reporter: Madhan Sundararajan Devaki
>            Priority: Critical

> Is there a plan to support updatable HAR Filesystem? If so, by when is this expected
please?
> The following operations may be supported.
> + Add new files [ -a filename-uri1 filename-uri2 ... / -a dirname-uri1 dirname-uri2 ...]
> + Remove existing files [ -d filename-uri1 filename-uri2 ... / -d dirname-uri1 dirname-uri2
...]
> + Update/Replace existing files (Optional) [ -u old-filename-uri new-filename-uri]
> This is required in cases where data is stored in AVRO format in HDFS and the corresponding
.avsc files are used to create Hive external tables.
> This will lead to the small files (.avsc files in this case) problem when there are a
large number of tables that need to be loaded into Hive as external tables.
