[jira] [Commented] (IOTDB-3384) [ query ] fetchResults failed. The validated expression is false
[ https://issues.apache.org/jira/browse/IOTDB-3384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17551417#comment-17551417 ]
Yuan Tian commented on IOTDB-3384:
----------------------------------
Debug后发现，SinkHandle计算出来的TsBlock的retainedSize与SourceHandle收到之后反序列化出来的TsBlock的retainedSize不一致（可以见log.txt），进一步跟踪代码，发现序列化时将RunLengthEncodedColumn当成普通的Column去序列化了，导致反序列时，并没有将其反序列化成[^log.txt]
