+title: Writing Data to HDFS
+---
+
+The PXF HDFS plug-in supports writable external tables using the
`HdfsTextSimple` and `SequenceWritable` profiles. You might create a writable
table to export data from a HAWQ internal table to HDFS.
+
+This section describes how to use these PXF profiles to create writable
external tables.
+
+**Note**: You cannot directly query data in a HAWQ writable table. After
creating the external writable table, you must create a HAWQ readable external
table accessing the HDFS file, then query that table. ??You can also create a
Hive table to access the HDFS file.??

This note could use some editing. Something like: Tables that you create
with the SequenceWritable profile can only be used for INSERT operations. If
you want to query the inserted data, you must define a separate external table
that references the new HDFS file, using the ???? or ??? profiles.
