Ambari does not support running or installing stacks on Unbuntu.
The component version information displayed by Ambari is based on the Ambari Stack definition. If you have applied patches to the Stack and to your software repository, that component version might differ from the actual version installed. There is no functional impact on Ambari if the patch versions mismatch. If you have any questions on component versions, refer to the rpm version installed on the actual host.
BUG-12111: Missing LzoCodec settings in
core-site.xml
fileProblem: After cluster install, the
io.compression.codecs
property in$HADOOP_CONF_DIR/core-site.xml
was incorrect. It displays as:<property> <name>io.compression.codecs</name> <value>org.apache.hadoop.io.compress.GzipCodec,org.apache.hadoop.io.compress.DefaultCodec</value> </property>
Workaround: Use Ambari Web to modify the
io.compression.codecs
property. Select Services > HDFS > Configs > Advanced and modify to:<property> <name>io.compression.codecs</name> <value>org.apache.hadoop.io.compress.GzipCodec,com.hadoop.compression.lzo.LzoCodec,org.apache.hadoop.io.compress.DefaultCodec</value> </property>
And add the
io.compression.codec.lzo.class
property to the Customcore-site.xml
section:<property> <name>io.compression.codec.lzo.class</name> <value>com.hadoop.compression.lzo.LzoCodec</value> </property>
