我在aws emr中运行sqoop。我正在尝试将一个表从mysql复制到hdfs中~10gb。
我得到以下例外

如果在没有“-direct”选项的情况下运行，则会得到如下所示的通信异常https://issues.cloudera.org/browse/sqoop-186
我已经在mysql中将“net write timeout”和“net read timeout”的值设置为6000。
我的sqoop命令如下所示

sqoop import -D mapred.task.timeout=0 --fields-terminated-by '\t' --escaped-by '\\' --optionally-enclosed-by '\"' --bindir ./ --connect jdbc:mysql://<remote ip>/<mysql db> --username tuser --password tuser --table table1 --target-dir=/base/table1 --split-by id -m 8 --direct

如何修复相同的问题？我错过了什么吗。
我还创造了sqoop jira-https://issues.apache.org/jira/browse/sqoop-2411
