-----------------------------------------
bq. * This issue is addressed in the [Java SDK 2.3.2
version|https://github.com/Azure/azure-data-lake-store-java/blob/dafdcdef608f13e951b0336a44307a7b5f1e894b/src/main/java/com/microsoft/azure/datalake/store/oauth2/AzureADAuthenticator.java#L266.]
Thank you. I spent a lot of time on a support call related to that and proxy
settings in distcp, especially the way that a parse failure in the error json
was raising an NPE. The whole [cloudstore
module|https://github.com/steveloughran/cloudstore] was written just to work
out what was going wrong
> Upgrade to ADLS SDK which has major performance improvement for ingress/egress
