I was able to resolve this issue after a lot of work.  Records in kafka had null values and S3 sink connector cannot write null values to S3 bucket and failed with this error, We were able to dig deeper when we changed the flush.size =1 and then we saw a different error and that made us check for null values.    We developed a patch that fixed the issue. now the S3 connector ignores null values . I dont know why confluent SMT did not work.  ... View more

It happened to me when I was installing cloudera 6.3.1, What solved to me was:   1. run:    sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config     2. config /etc/hosts: (just an exemple, set the host of all machines)   hostnamectl set-hostname master1.hadoop-test.com echo "10.99.0.175 master1.hadoop-test.com master1" >> /etc/hosts sed -i 's/\r//' /etc/hosts echo "HOSTNAME=master1.hadoop-test.com" >> /etc/sysconfig/network     3.   reboot     then: 4.  wget <a href="https://archive.cloudera.com/cm6/6.3.1/cloudera-manager-installer.bin" target="_blank">https://archive.cloudera.com/cm6/6.3.1/cloudera-manager-installer.bin</a>     5.    chmod u+x cloudera-manager-installer.bin   6.    ./cloudera-manager-installer.bin     ...

The Disk Balancer sub-system is local to each DataNode and can be triggered on distinct hosts in parallel. The only time you should receive that exception is if the targeted DN's hdfs-site.xml does not carry the property that enables disk balancer, or when the DataNode is mid-shutdown/restart. How have you configured disk balancer for your cluster? Did you follow the configuration approach presented at https://blog.cloudera.com/blog/2016/10/how-to-use-the-new-hdfs-intra-datanode-disk-balancer-in-apache-hadoop/? What is your CDH and CM version? ... View more
