Question

我正在创建一个如下所示的spring xd流：

stream create foo --definition "jdbc --url=jdbc:mysql://localhost:3306/test --driverClassName=com.mysql.jdbc.Driver --query='select * from employee' |hdfs --inputType=text/plain --rollover=200" --deploy

我能够在hdfs中获取数据。但我在下面的日志中收到错误。这种错误的任何原因..
输出在这里：

-rw-r--r--   3 root hdfs        216 2015-10-15 08:45 /xd/foo/foo-34.txt
-rw-r--r--   3 root hdfs        216 2015-10-15 08:45 /xd/foo/foo-35.txt
-rw-r--r--   3 root hdfs        216 2015-10-15 08:45 /xd/foo/foo-36.txt
-rw-r--r--   3 root hdfs          0 2015-10-15 08:45 /xd/foo/foo-37.txt.tmp

但错误是在日志文件中

我有时也遇到过这个问题。我打开了一个JIRA问题来研究这个问题：https://jira.spring.io/browse/XD-3620

与此同时，您可以在创建作业或流时指定“--testOnBorrow = false”来解决此问题。

mysql中的SpringXD问题作为源.FAILED验证新建立的连接
