Andrew Wang commented on HDFS-11956: ------------------------------------ bq. Maybe the forward compatibility of StorageTypes is another JIRA I should raise? Sure, would certainly be great to support this if possible. If not, there is precedence for requiring a client upgrade to use new features, like encryption or EC. bq. What's your time frame for tagging alpha4? I'm going to be travelling for a while starting July 8th, so my hope was Monday June 26th so there's some slack in the schedule. Since reverting seems like an okay solution, we don't need to feel pressured for this JIRA. > Fix BlockToken compatibility with Hadoop 2.x clients > ---------------------------------------------------- > > Key: HDFS-11956 > URL: https://issues.apache.org/jira/browse/HDFS-11956 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 3.0.0-alpha4 > Reporter: Andrew Wang > Assignee: Ewan Higgs > Priority: Blocker > Attachments: HDFS-11956.001.patch, HDFS-11956.002.patch, > HDFS-11956.003.patch > > > Seems like HDFS-9807 broke backwards compatibility with Hadoop 2.x clients. > When talking to a 3.0.0-alpha4 DN with security on: > {noformat} > 2017-06-06 23:27:22,568 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: > Block token verification failed: op=WRITE_BLOCK, > remoteAddress=/172.28.208.200:53900, message=Block token with StorageIDs > [DS-c0f24154-a39b-4941-93cd-5b8323067ba2] not valid for access with > StorageIDs [] > {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
