I got two hdfs-sink connections, in the config, the first will get data from topic 1 and sink to /hdfs/url1 (user1, using keytab1), the second will get data from topic 2 and sink to /hdfs/url2 (user2, using keytab2).
But in fact, the first sink was using the keytab2.
Hear are my configs:
the first hdfs-sink, user:ywmy, write to hdfs://bigdata-test/user/nd_ywmy/raw-data/realtime:

{
    "connector.class": "io.confluent.connect.hdfs.HdfsSinkConnector",

    "name": "ywmy-hdfs-sink",
    "path.format": "YYYYMMdd",
    "rotate.schedule.interval.ms": "86400000"
}

the second hdfs-sink, user:xhmy, write data to hdfs://bigdata-test/user/nd_xhmy/raw-data/realtime

{
    "connector.class": "io.confluent.connect.hdfs.HdfsSinkConnector",

According to the log, we can find that the first hdfs-sink tried to use user xhmy(keytab2) to write data to hdfs/url1(hdfs://bigdata-test/user/nd_ywmy/raw-data/realtime/logs/log-ywmy/9/log)
