Flume Compilation Error (1.5.0) for Hadoop 2.x and HBase 0.98

Hi,

I need to to compile Flume 1.5.0 for Hadoop 2.4.0 and HBase 0.98.3, the compilation returns warning and error,

I am new to Flume, could anyone share the correct settings for pom.xml files or advise the proper changes?

1) pom.xml
2) flume-ng-sinks/flume-hdfs-sink/pom.xm
3) flume-ng-sinks/flume-ng-hbase-sink/pom.xml
4) flume-ng-sinks/flume-ng-morphline-solr-sink/pom.xml

Many thanks!!
Arthur
