1、Could not find first log file name in binary log index file

canal解析binlog异常 ，meta.dat中记录的binlog日志文件不存在

ERROR c.a.o.canal.parse.inbound.mysql.dbsync.DirectLogFetcher - I/O error while reading from client socket
java.io.IOException: Received error packet: errno = 1236, sqlstate = HY000 errmsg = Could not find first log file name in binary log index file

2、Canal有计划支持基于GTID去做数据同步么 #126

https://github.com/alibaba/canal/issues/126

3、The slave is connecting using CHANGE MASTER TO MASTER_AUTO_POSITION = 1, but the master has purged binary logs containing GTIDs that the slave requires

4、开启GTID主从同步出现1236错误问题
