Hadoop

Taylor Goetz discusses improvements in Storm 1.0:

The log file viewer added in the Apache Storm 0.9.1 release made accessing Storm’s log files significantly easier, but in some cases still required examination individual log files one-by-one. In Storm 1.0 the UI now includes a powerful search feature that allows you to search a specific topology log file, or across all topology log files in the cluster, even archived files.

When performing a topology-wide search, the UI will search across all supervisor nodes for a match. The search results include a link to the matching log file, as well as host and port information that allow you quickly identify on which machine a specific log event occurred. This feature is particularly helpful when trying to track down when and where a particular error occurred.

The examples Taylor gives are all built around scaling.  When you have dozens or hundreds of nodes, one-by-one solutions just don’t work.
