• Q & A

4. is a distributed real-time monitoring and alerting
engine for hadoop from eBay
Open sourced as Apache Incubator Project on Oct 26th 2015
Secure Hadoop in Realtime a data activity monitoring solution to instantly identify
access to sensitive data, recognize attacks/ malicious activity and block access in real
time.
See http://eagle.incubator.apache.org or http://github.com/apache/incubator-eagle
Apache Eagle

5. Eagle
was
initialized
by
end
of
2013
for
hadoop ecosystem
monitoring
as
any
existing
tool
like
zabbix,
ganglia
can
not
handle
the
huge
volume
of
metrics/logs
generated
by
hadoop system
in
eBay.
