> ---------------------------------------------------------------------

> Key: SPARK-8619
> URL: https://issues.apache.org/jira/browse/SPARK-8619
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.5.0
> Reporter: SaintBacchus
>
> In a streaming application, I use *--keytab /root/spark.keytab* to get the token.
> But when the streaming application failed and I wanted to recover it from checkpoint file, there was an error:
> {quote}
> java.io.IOException: Login failure for spark/hadoop.hadoop.com@HADOOP.COM from keytab spark.keytab-1fd8f7bb-0d3c-4f65-990a-9ae09055cc8d: javax.security.auth.login.LoginException: Unable to obtain password from user
> {quote}
> Spark had changed the configuration, so the checkpoint can't find the file:
> {code:title=Client.java @ Function: setupCredentials |borderStyle=solid}
> val keytabFileName = f.getName + "-" + UUID.randomUUID().toString
> UserGroupInformation.loginUserFromKeytab(args.principal, args.keytab)
> loginFromKeytab = true
> sparkConf.set("spark.yarn.keytab", keytabFileName)
> {code}
> So when recovering the application, we should ignore this configurations.
