-----------------------------------
Summary: AdlStoreClient#getExceptionFromResponse should not
swallow defaultMessage
Key: HADOOP-14304
URL: https://issues.apache.org/jira/browse/HADOOP-14304
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/adl
Affects Versions: 2.8.0
Reporter: John Zhuge
Discovered the issue in HADOOP-14292.
In {{AdlStoreClient}}, {{enumerateDirectoryInternal}} called
{{getExceptionFromResponse}} with {{defaultMessage}} set to {{"Error
enumerating directory " + path}}. This useful message was swallowed at
https://github.com/Azure/azure-data-lake-store-java/blob/2.1.4/src/main/java/com/microsoft/azure/datalake/store/ADLStoreClient.java#L1106.
Actually {{getExceptionFromResponse}} swallows {{defaultMessage}} at several
places. Suggest always displaying the {{defaultMessage}} in some way.
