Description

Currently, WASB driver uses the default value false for kerberosSupportEnabled in org.apache.hadoop.fs.azure.NativeAzureFileSystem which results in skipping the logic of fetching the delegation token from the remote service in secure mode (introduced in HADOOP-13945), which is incorrect.
Fix is to initialize kerberosSupportEnabled instance member with value of the configuration property fs.azure.enable.kerberos.support.
