> NativeAzureFileSystem does not support setXAttr
> -----------------------------------------------
>
> Key: HADOOP-16005
> URL: https://issues.apache.org/jira/browse/HADOOP-16005
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Reporter: Clemens Wolff
> Assignee: Clemens Wolff
> Priority: Major
>
> When interacting with Azure Blob Storage via the Hadoop FileSystem client, it's currently (as of [a8bbd81|https://github.com/apache/hadoop/commit/a8bbd818d5bc4762324bcdb7cf1fdd5c2f93891b]) not possible to set custom metadata attributes.
> Here is a snippet that demonstrates the missing behavior (throws an UnsupportedOperationException):
> {code:java}
> val blobAccount = "SET ME"
> val blobKey = "SET ME"
> val blobContainer = "SET ME"
> val blobFile = "SET ME"
> import org.apache.hadoop.conf.Configuration
> import org.apache.hadoop.fs.{FileSystem, Path}
> val conf = new Configuration()
> conf.set("fs.wasbs.impl", "org.apache.hadoop.fs.azure.NativeAzureFileSystem")
> conf.set(s"fs.azure.account.key.$blobAccount.blob.core.windows.net", blobKey)
> val path = new Path(s"wasbs://$blobContainer@$blobAccount.blob.core.windows.net/$blobFile")
> val fs = FileSystem.get(path, conf)
> fs.setXAttr(path, "somekey", "somevalue".getBytes)
> {code}
> Looking at the code in hadoop-tools/hadoop-azure, NativeAzureFileSystem inherits the default setXAttr from FileSystem which throws the UnsupportedOperationException.
> The underlying Azure Blob Storage service does support custom metadata ([service docs|https://docs.microsoft.com/en-us/azure/storage/blobs/storage-properties-metadata]) as does the azure-storage SDK that's being used by NativeAzureFileSystem ([SDK docs|http://javadox.com/com.microsoft.azure/azure-storage/2.0.0/com/microsoft/azure/storage/blob/CloudBlob.html#setMetadata(java.util.HashMap)]).
> Is there another way that I should be setting custom metadata on Azure Blob Storage files? Is there a specific reason why setXAttr hasn't been implemented on NativeAzureFileSystem? If not, I can take a shot at implementing it.
