Hi Vasco, Do you use any Hadoop distribution like Cloudera or Hortonworks that automatically configures YARN/MR to work on the cluster. I've tried to reproduce your error on my training cluster (CDH-5.8.0, HBase 1.2.0) and the export works fine.
It says /17/04/27 08:56:26 WARN mapreduce.TableMapReduceUtil: The hbase-prefix-tree module jar containing PrefixTreeCodec is not present. Continuing without it./ See logs here: https://pastebin.com/GNyn62Nq Can you double check that YARN & MapReduce client libraries and configuration files are available on the node that you run the Export job? Can you also run "grep -R "local" /etc/hadoop/conf" on the node that you run the Export job? -- View this message in context: http://apache-hbase.679495.n3.nabble.com/Hbase-exportSnapshot-fails-in-HA-missing-hbase-prefix-tree-jar-tp4087506p4087720.html Sent from the HBase User mailing list archive at Nabble.com.
