Nodes down

[Rodrigo Felix <ro...@gmail.com>]

I`m running YCSB and sometimes, when the load is heavy, some nodes get down.

What does the first line of bin/nodetool ring output means? It has the same
token of the down node. For each down node, is it expected to be shown a
line like the first one (with most columns empty)?

No, it doesn't. It is displaying the token of the highest node to
indicate to you that the token range is a ring, and that the first
node in your cluster has a primary range "between" the highest token
(113427455640312821154458202477256070484 ) and the lowest token (0).

No.
