Ted Yu commented on HBASE-20894:
--------------------------------
I was running related unit tests and got the following ?
{code}
testRetrieveFromFile[0: blockSize=8,192,
bucketSizes=null](org.apache.hadoop.hbase.io.hfile.bucket.TestBucketCache)
Time elapsed: 1.15 sec <<< ERROR!
org.apache.hbase.thirdparty.com.google.protobuf.UninitializedMessageException:
Message missing required fields: access_counter
at
org.apache.hadoop.hbase.io.hfile.bucket.TestBucketCache.testRetrieveFromFile(TestBucketCache.java:266)
testRetrieveFromFile[1: blockSize=16,384,
bucketSizes=[I@2ef5e5e3](org.apache.hadoop.hbase.io.hfile.bucket.TestBucketCache)
Time elapsed: 0.262 sec <<< ERROR!

{code}
Can you check whether access_counter field can be optional ?
Thanks
