> Certain HDP installations - eg HBase version 1.1.2.2.3.4.7-4 does not have the directory "/usr/hdp/current/hadoop-client/client/.
> Currently this is how the hadoop JARs are picked up for HDP.
> export HADOOP_JAR_FILES="/usr/hdp/current/hadoop-client/client/hadoop-hdfs-*.jar"
> SO in some installations this JAR isn't foudn and calls to HDFS interface fail with this kind of an error :
> *** ERROR[8448] Unable to access Hbase interface. Call to ExpHbaseInterface::addToHFile returned error HBASE_ADD_TO_HFILE_ERROR(-713). Cause: java.io.IOException: No FileSystem for scheme: hdfs
> org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2644)
> org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2651)
> org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:92)
> org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2687)

> org.trafodion.sql.HBulkLoadClient.doCreateHFile(HBulkLoadClient.java:182)
> org.trafodion.sql.HBulkLoadClient.addToHFile(HBulkLoadClient.java:226).
> *** ERROR[1081] Loading of index TRAFODION.SEABASE.I failed unexpectedly.
> Need to change the path to the hadoop-hdfs.jar file to be :
> export HADOOP_JAR_FILES="/usr/hdp/current/hadoop-hdfs-client/hadoop-hdfs-*.jar
> This si related to changes made in this 2 JIRAs. At some point, the directory current/hadoop-client was dropped from the distribution.
