Hi Hadoopians,
I'm a noob in hadoop (what a rhyme) ....and got some questions relating to the
white papers posted on cloudera.com as follows:
in IQT QUARTERLY: HADOOP: Scalable, Flexible Data Storage and Analysis - By
Mike Olson
I got an antagonism when comparing case studies and the following pros&cons
of hadoop.
pros: hadoop(M/R) mostly used in batch operation (running mins or hours to
complete)
cons: hadoop(M/R) not usable for interactive applications
and the case study: OpenPDC where it is used for monitoring and to be able
to react quickly:
"Close monitoring and rapid response to changes in the state of the
grid
allow utilities to minimize or prevent blackouts,"
another case study from "Ten Common Hadoopable Problems - Real-World Hadoop
Use Cases":
"Fast detection allows the bank to protect itself from considerable
losses."
If there is a better non-commercial place to ask this questions please let me
know.
Background: I'm intending to set up a system for another domain where lots of
sensordata need to be stored
and queried to implement monitoring an detect problem situations
kind regards
Christian
