 Hi Shahid,
 To be honest I think this question is better suited for Stack Overflow
 than for a PhD thesis.

 hi

 I have a 10 node cluster  i loaded the data onto hdfs, so the no. of
 partitions i get is 9. I am running a spark application , it gets stuck on
 one of tasks, looking at the UI it seems application is not using all nodes
 to do calculations. attached is the screen shot of tasks, it seems tasks
 are put on each node more then once. looking at tasks 8 tasks get completed
 under 7-8 minutes and one task takes around 30 minutes so causing the delay
 in results.

 Hi,

 I am doing my PHD thesis on large scale machine learning e.g  Online
 learning, batch and mini batch learning.

 Could somebody help me with ideas especially in the context of Spark and
 to the above learning methods.

 Some ideas like improvement to existing algorithms, implementing new
 features especially the above learning methods and algorithms that have not
 been implemented etc.

 If somebody could help me with some ideas it would really accelerate my
 work.

 Plus few ideas on research papers regarding Spark or Mahout.

 Thanks in advance.

 Regards
