Re：Exception : Incorrect byte array size in eventserver

Posted by 李伟 <li...@foxmail.com>.
I met same exception while importing a data file exported from MySQL eventserver into hbase eventserver.


Data rows like this:
{"eventId":"0002e945e06c4ba79e360e92ce4376d4","event":"$set","entityType":"item","entityId":"Galaxy","properties":{"categories":["Phones","Electronics","Samsung"]},"eventTime":"2017-10-05T23:48:30.000Z","creationTime":"2017-11-09T09:24:33.000Z"}





The data file exported from hbase eventserver can be imported successfully.
Data rows like this:
{"eventId":"KpjNMVrQzY2s0TZhYB3vsAAAAV3jJ35Dpq6EWTaWJLM","event":"$set","entityType":"item","entityId":"Nexus","properties":{"defaultRank":4.0,"expires":"2017-11-10T14:14:02.563101+00:00","countries":["United States","Canada"],"date":"2017-11-08T14:14:02.563101+00:00","categories":["Tablets","Electronics","Google"],"available":"2017-11-06T14:14:02.563101+00:00"},"eventTime":"2017-11-09T09:26:08.938Z","creationTime":"2017-11-09T09:26:08.938Z"}

it seems like a eventId format problem.


Does anyone have any idea about this problem?


Thanks
