Page Blob Support and Configuration
|
||||
===================================
|
||||
|
||||
The Azure Blob Storage interface for Hadoop supports two kinds of blobs, block blobs
|
||||
and page blobs. Block blobs are the default kind of blob and are good for most
|
||||
big-data use cases, like input data for Hive, Pig, analytical map-reduce jobs etc.
|
||||
Page blob handling in hadoop-azure was introduced to support HBase log files.
|
||||
Page blobs can be written any number of times, whereas block blobs can only be
|
||||
appended to 50,000 times before you run out of blocks and your writes will fail.
|
||||
That won't work for HBase logs, so page blob support was introduced to overcome
|
||||
this limitation.
|
||||
|
||||
Page blobs can be used for other purposes beyond just HBase log files though.
|
||||
They support the Hadoop FileSystem interface. Page blobs can be up to 1TB in
|
||||
size, larger than the maximum 200GB size for block blobs.
|
||||
|
||||
In order to have the files you create be page blobs, you must set the configuration
|
||||
variable fs.azure.page.blob.dir to a comma-separated list of folder names.
|
||||
E.g.
|
||||
|
||||
/hbase/WALs,/hbase/oldWALs,/data/mypageblobfiles
|
||||
|
||||
You can set this to simply / to make all files page blobs.
|
||||
|
||||
The configuration option fs.azure.page.blob.size is the default initial
|
||||
size for a page blob. It must be 128MB or greater, and no more than 1TB,
|
||||
specified as an integer number of bytes.
|
||||
|
||||
====================
|
||||
Atomic Folder Rename
|
||||
====================
|
||||
|
||||
Azure storage stores files as a flat key/value store without formal support
|
||||
for folders. The hadoop-azure file system layer simulates folders on top
|
||||
of Azure storage. By default, folder rename in the hadoop-azure file system
|
||||
layer is not atomic. That means that a failure during a folder rename
|
||||
could, for example, leave some folders in the original directory and
|
||||
some in the new one.
|
||||
|
||||
HBase depends on atomic folder rename. Hence, a configuration setting was
|
||||
introduced called fs.azure.atomic.rename.dir that allows you to specify a
|
||||
comma-separated list of directories to receive special treatment so that
|
||||
folder rename is made atomic. The default value of this setting is just /hbase.
|
||||
Redo will be applied to finish a folder rename that fails. A file
|
||||
<folderName>-renamePending.json may appear temporarily and is the record of
|
||||
the intention of the rename operation, to allow redo in event of a failure.
