Travis builds fail due to missing com.hadoop.gplcompression:hadoop-lzo:jar:0.4.16. See details in the Travis log. Issue is reproducible locally be removing hadoop-lzo from the local maven repository and starting the build.
See more details about the issue in the hadoop-lzo bug tracking.
hadoop-lzo is not required for build/test parquet-mr; it is a transitive dependency pulled in by elephant-bird-core. Possible fix is to exclude hadoop-lzo from the dependency tree.
