------------------------------------
Priority: Minor (was: Major)
> azure datalake AzureADAuthenticator failing, no error info provided
> -------------------------------------------------------------------
>
> Key: HADOOP-15188
> URL: https://issues.apache.org/jira/browse/HADOOP-15188
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/adl
> Affects Versions: 3.0.0, 3.1.0
> Reporter: Steve Loughran
> Assignee: Atul Sikaria
> Priority: Minor
>
> Get a failure in ADLS client, but nothing useful in terms of failure
> description
> {code}
> DEBUG oauth2.AzureADAuthenticator: AADToken: starting to fetch token using
> client creds for client ID <omitted>
> DEBUG store.HttpTransport:
> HTTPRequest,Failed,cReqId:<omitted>,lat:127370,err:HTTP0(null),Reqlen:0,Resplen:0,token_ns:<omitted>,sReqId:null,path:<omitted>,qp:op=GETFILESTATUS&tooid=true&api-version=2016-11-01
> {code}
> so: we had a failure but the response code is 0, error(null); "something
> happened but we don't know what"
> Looks like this log message is in the ADLS SDK, and can be translated like
> this.
> {code}
> String logline =
> "HTTPRequest," + outcome +
> ",cReqId:" + opts.requestid +
> ",lat:" + Long.toString(resp.lastCallLatency) +
> ",err:" + error +
> ",Reqlen:" + length +
> ",Resplen:" + respLength +
> ",token_ns:" + Long.toString(resp.tokenAcquisitionLatency) +
> ",sReqId:" + resp.requestId +
> ",path:" + path +
> ",qp:" + queryParams.serialize();
> {code}
> It looks like whatever code tries to parse the JSON response from the OAuth
> service couldn't make sense of the response, and we end up with nothing back.
> Not sure what can be done in hadoop to handle this, except maybe provide more
> diags on request failures.
