| <p>Here is a list of frequently asked questions.</p> |
| <ul> |
| <li>Why does my Giraph job randomly fail after hundreds of supersteps? |
| <ul> |
| <li>In Hadoop 0.20.203.0 onwards, there is a limit on the number of counters one can use, which is set to 120 by default. This limit restricts the number of iterations/supersteps possible in Giraph. This limit can be increased by setting a parameter <tt>mapreduce.job.counters.limit</tt> in job tracker's config file mapred-site.xml.</li> |
