I got this error message when running `./testdata/bin/run-mini-dfs.sh`:

Failed to start hdfs-namenode. The end of the log

log4j:ERROR Could not instantiate appender named "EventCounter". {code}
I also found that EventCounter is not in hadoop-common-*.jar by running:
{code:java}
jar tf $HADOOP_HOME/share/hadoop/common/hadoop-common-*.jar | grep EventCounter
{code}
It turns out that HADOOP-17524 has removed EventCounter. Since the default
version for Apache Hadoop has been updated to 3.4.1 in IMPALA-13753,
log4j.properties files should also be updated to start HDFS cluster with newer
versions.
