Big Data Management Known Limitations (10.2.2 HotFix 1)

The following table describes known limitations:

Bug	Description
BDM-26248	If you specify a compression codec in a custom query, the Blaze engine fails to compress HDFS files using the codec on every Hadoop distribution except Hortonworks HDP 3.1.
BDM-26206	A mapping with flat file sources and targets that uses the Spark engine to run on a WANdisco-enabled Hortonworks HDP 2.6.5 cluster fails. Workaround: Copy the following .jar files from the cluster in the usr/hdp/<version>/hadoop/client directory to each node where the Informatica Data Integration Service is installed to the <Informatica home>/services/shared/spark/lib_spark_<version> directory: hadoop-common-x.x.x.jar hadoop-auth-x.x.x.jar where "x.x.x" is the .jar file version that WANdisco uses. For example, find the file hadoop-common-2.7.3.2.6.5.0-292.jar in the /usr/hdp/2.6.5.0-292/hadoop/client directory on the cluster. Restart the Data Integration Service on each node. On the cluster node where HDFS sources/targets reside, grant 733 permisson to HDFS.
BDM-25475	When you delete contents for Erasure Coding (EC) within the cluster staging directory and run the mapping, the mapping might fail when the auto installer copy sometimes fails to create the XOR codec for raw EC.
