1) i am using below commands for coping data
COPY events.standardevents (uuid, data, name, time, tracker, type, userid)
TO 'temp.csv';
truncate standardevents;
COPY event.standardeventstemp (uuid, data, name, time, tracker, type,
userid) FROM 'temp.csv';
if table is not containing any field with uuid data-type above commands are
working fine but if it is containig data-type as a uuid then it is giving me
below error
Bad Request: Invalid STRING constant (3a1ccec0-ef77-11e3-9e56-22000ae3163a)
for name of type uuid
aborting import at column #0, previously inserted values are still present.
Below is the description of my column-family
CREATE TABLE standardevents (
uuid uuid PRIMARY KEY,
data text,
name text,
time text,
tracker text,
type text,
userid text
) WITH
bloom_filter_fp_chance=0.010000 AND
caching='KEYS_ONLY' AND
comment='' AND
dclocal_read_repair_chance=0.000000 AND
gc_grace_seconds=864000 AND
read_repair_chance=0.100000 AND
replicate_on_write='true' AND
populate_io_cache_on_flush='false' AND
compaction={'class': 'SizeTieredCompactionStrategy'} AND
compression={'sstable_compression': 'SnappyCompressor'};
2) Facing problem of Heap is 0.8116662666877581 full
checked the logs getting below messages
GCInspector.java (line 142) Heap is 0.8116662666877581 full. You may need
to reduce memtable and/or cache sizes. Cassandra will now flush up to the
two largest memtables to free up memory. Adjust flush_largest_memtables_at
threshold in cassandra.yaml if you don't want Cassandra to do this
automatically
StorageService.java (line 3512) Unable to reduce heap usage since there are
no dirty column families
i checked the cassandra-en.sh file currently it is occuping
MAX_HEAP_SIZE="4G"
HEAP_NEWSIZE="800M" which i guess is maximum.
because of this constanly getting heap size error on every command.
