Add support for Apache Hadoop 2.x in Celeborn build Developers need to only specify their `hadoop.version`, and the build will pick the right profile internally based on the version to add the relevant dependencies. [hadoop-client-api](https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-client-api) and [hadoop-client-runtime](https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-client-runtime) were introduced in hadoop 3.x, while hadoop 2.x had [hadoop-client](https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-client) Celeborn depends on the former, and so requires hadoop 3.x to build. Apache Spark dropped support for Hadoop 2.x only in the recent v3.5 ([SPARK-42452](https://issues.apache.org/jira/browse/SPARK-42452)). Given this, we have case where deployments on supported platforms like Spark 3.4 and older running on 2.x hadoop, will need to pull in hadoop 3.x just for Celeborn. This PR uses `hadoop-client` when `hadoop.version` is specified as 2.x - and preserves existing behavior when `hadoop.version` is 3.x Note - while using `hadoop-client` in 3.x is an option, hadoop community recommendation is to rely on `hadoop-client-api`/`hadoop-client-runtime`, hence making an effort to leverage that as much as possible. Adds support for using 2.x for hadoop.version Three combinations were tested: * Default, without overriding hadoop.version Dependencies: ``` $ build/mvn dependency:list 2>&1 | grep hadoop | sort | uniq [INFO] org.apache.hadoop:hadoop-client-api:jar:3.2.4:compile [INFO] org.apache.hadoop:hadoop-client-runtime:jar:3.2.4:compile ``` Will update this section again based on test suite results (which are ongoing) * Setting hadoop.version to newer 3.3.0 explicitly Dependencies: ``` $ ARGS="-Pspark-3.1 -Dhadoop.version=3.3.0" ; build/mvn dependency:list $ARGS 2>&1 | grep hadoop | sort | uniq [INFO] org.apache.hadoop:hadoop-client-api:jar:3.3.0:compile [INFO] org.apache.hadoop:hadoop-client-runtime:jar:3.3.0:compile ``` * Setting hadoop.version to older 2.10.0 Dependencies: ``` $ ARGS="-Pspark-3.1 -Dhadoop.version=2.10.0" ; build/mvn dependency:list $ARGS 2>&1 | grep hadoop | grep compile | sort | uniq [INFO] org.apache.hadoop:hadoop-auth:jar:2.10.0:compile -- module hadoop.auth (auto) [INFO] org.apache.hadoop:hadoop-client:jar:2.10.0:compile -- module hadoop.client (auto) [INFO] org.apache.hadoop:hadoop-common:jar:2.10.0:compile -- module hadoop.common (auto) [INFO] org.apache.hadoop:hadoop-hdfs-client:jar:2.10.0:compile -- module hadoop.hdfs.client (auto) [INFO] org.apache.hadoop:hadoop-mapreduce-client-app:jar:2.10.0:compile -- module hadoop.mapreduce.client.app (auto) [INFO] org.apache.hadoop:hadoop-mapreduce-client-common:jar:2.10.0:compile -- module hadoop.mapreduce.client.common (auto) [INFO] org.apache.hadoop:hadoop-mapreduce-client-core:jar:2.10.0:compile -- module hadoop.mapreduce.client.core (auto) [INFO] org.apache.hadoop:hadoop-mapreduce-client-jobclient:jar:2.10.0:compile [INFO] org.apache.hadoop:hadoop-mapreduce-client-shuffle:jar:2.10.0:compile -- module hadoop.mapreduce.client.shuffle (auto) [INFO] org.apache.hadoop:hadoop-yarn-api:jar:2.10.0:compile -- module hadoop.yarn.api (auto) [INFO] org.apache.hadoop:hadoop-yarn-common:jar:2.10.0:compile -- module hadoop.yarn.common (auto) ``` For each of the case above, build/test passes for each of the `ARGS`.
