Uma Maheswara Rao Gangumalla
I am currently working on the
an open source distributed computing system,
Intel Corporation. I am also a Committer and PMC for the Apache Hadoop project and a committer for BookKeeper project.
Prior to Intel I worked at Huawei as Technical lead.
With Huawei, I was also part of Namenode high availability implementation HDFS-1623.
Also I worked on making the BookKeeper as shared storage in Namenode HA and Presented this work at Beijing Big Data Conference. And also click here for slides
Take a look at LADIS presentation by Flavio for more details about BookKeeper use cases. Click here
I also played key role in design and development of the BookKeeper autorecovery feature.
Prior to this, we have implemented HA on Hadoop-1 using Backup Node approach
and running with some of the internal customers from the year 2011.
Before I joined in Hadoop team, I was involved in SIP servelet container development at Huawei.
We have developed HA for SIP containers and capable of running with 1200 Caps,
which is very high perpormed container than competetors like Oracle containers
We have build a OSGI container with equinox libraries, and SIP container will run on OSGI platform
Recent design documents we worked at Intel:
Hadoop disaster recovery
Hadoop Chriptographic FileSystem
HDFS Extended Attributes
